                 The Arizona Acquisition.  On September 15, 1997, the

Associates Southwest is a three physician sub-specialty retina practice with two

merger of Retina Associates Southwest into the Registrant. As consideration for
the acquisition, the shareholders of Retina Associates Southwest received a
total of $4,102,340 consisting of $1,846,053 in cash and 219,057 shares of
common stock of the Registrant.  The consideration is subject to certain
post-closing adjustments. As a result of the merger of Retina Associates
Southwest into the Registrant, the Registrant will assume Retina Associates
Southwest's role as business manager under a 40 year management agreement
between Retina Associates Southwest and a newly-formed Arizona professional
corporation to which Retina Associates Southwest will have transferred all of
its medical assets prior to the merger.

                 The Florida Acquisitions.  On September 17, 1997, Vision
Twenty-One, Inc. (the "Registrant") closed the acquisition of the non-medical
assets of Florida Eye Center in escrow pending finalization of certain closing
items.  Florida Eye Center, which is located in Tampa, Florida, is a five
ophthalmologist multi-specialty practice with two locations and an optical
dispensary, Center Optical, Inc.  Florida Eye Center is a partnership and the
partners of Florida Eye Center are Florida Eye Center, Sever & Ramseur, M.D.,
P.A. ("Sever & Ramseur P.A."), Thomas J. Pusateri, M.D., P.A. ("Pusateri P.A."),
and Leonard E. Cortelli, M.D., P.A. ("Cortelli P.A.").  The acquisition is being
accomplished by a merger of Sever & Ramseur P.A. into the Registrant, by the
sale of the non-medical assets of Pusateri P.A., and Cortelli P.A. to the
Registrant, and by the sale of the non-optical assets of Center Optical, Inc. to
the Registrant. The total consideration to be paid for the acquisition is
$2,877,864 consisting of $1,274,132 in cash and 155,702 shares of stock of the
Registrant. The consideration is subject to certain post-closing adjustments. As
a result of the merger of Sever & Ramseur P.A. into the Registrant, the
Registrant will assume Sever & Ramseur P.A.'s role as business manager under a
40 year management agreement between Sever & Ramseur P.A. and Sever, Pusateri &
Cortelli, M.D., P.A., a newly-formed Florida professional association to which
each of Sever & Ramseur P.A., Pusateri P.A., Cortelli P.A. and Center Optical,
Inc. will have transferred all of their medical or optical assets.

                 In a related acquisition, the Registrant also closed in escrow
the acquisition of the Managed Health Services, a managed care company owned by
Drs. Sever, Ramseur, Pusateri and Cortelli located in Tampa, Florida and
consisting of 28 contract providers.  The acquisition is being accomplished by
the sale of the assets of Managed Health Services to the Registrant.  The total
consideration to be paid for the acquisition is $1,618,410 consisting of
$434,603 in cash to be paid at closing and contingent consideration to be held
in escrow in an amount equal to $394,603 in cash and $789,205 represented by
76,622 shares of common stock of the Registrant, the amount of such contingent
consideration to be paid to be determined based upon the medical loss ratio
relating to certain capitated medical surgery eye care contracts for the period
ending August 31, 1998. The consideration is subject to certain post-closing 
adjustments.

                 The Florida and Arizona acquisitions will be accounted for as
a "purchase" for financial reporting purposes.

                      AGREEMENT AND PLAN OF REORGANIZATION

         This Agreement and Plan of Reorganization (this "Agreement"), effective
as of September 1, 1997, is by and among FLORIDA EYE CENTER, SEVER & RAMSEUR,
M.D., P.A., a Florida professional association (the "Company"), RAYMOND J.
SEVER, M.D. and HENRY M. RAMSEUR, M.D. (together, the "Physician"), and VISION
TWENTY-ONE, INC., a Florida corporation ("Vision 21").

                                    RECITALS

         A.       Physician is a physician licensed to practice medicine in the
State (as defined herein) and currently employs ophthalmology employees and
conducts an ophthalmology practice through the Company and through a Florida
partnership known as Florida Eye Center (the "Partnership"), of which the
Company is a partner.

         B.       Physician owns all of the issued and outstanding shares of
capital stock of the Company.

         C.       The Company and Vision 21 desire to effect a business
combination and merger of the Company with and into Vision 21 upon the terms and
subject to the satisfaction of the conditions precedent contained herein (the
"Merger").

         D.       Simultaneously herewith, Leonard E. Cortelli, Jr., M.D., P.A.,
a Florida professional association ("Cortelli, P.A."), and Thomas J. Pusateri,
M.D., P.A., a Florida professional association ("Pusateri, P.A.") (which
professional associations, together with the Company, comprise all of the
partners of the Partnership) shall each enter into an Asset Purchase Agreement
with Vision 21.

         E.       Simultaneously herewith, but prior to the Merger, the
Partnership shall distribute all of its assets and assign all of its liabilities
to Cortelli, P.A., Pusateri, P.A. and the Company.

         F.       It is intended that for federal income tax purposes the Merger
shall qualify as a reorganization within the meaning of Section 368(a)(1)(A) of
the Internal Revenue Code of 1986, as amended (the "Code").

         G.       Vision 21 cannot acquire certain of the Company's assets
because of laws prohibiting general business corporations from engaging in the
practice of medicine or optometry, exercising control over physicians practicing
medicine or optometrists practicing optometry, or engaging in certain practices
such as fee-splitting with physicians or optometrists, and accordingly, the
Company and Vision 21 desire that the Company divest itself of such assets prior
to the Merger.

         H.       Prior to the Merger, the Company, Cortelli, P.A. and Pusateri,
P.A. intend to form a new professional association ("New P.A.") to which the
Company intends to transfer its medical




<PAGE>   2

and optometry business, all of its Medical Assets (as defined herein) and all of
the Excluded Liabilities (as defined herein) in exchange for shares of New
P.A.'s capital stock, which the Company intends to distribute to Physician.

         I.       New P.A. intends to employ the Physician and enter into a
Business Management Agreement (as defined herein) with the Company immediately
prior to the Merger.

         J.       As a result of the Merger, the Surviving Corporation (as
defined herein) will acquire the medical and optometry practice management
business and all of the Nonmedical Assets (as herein defined) of the Company
associated with such business to the extent permitted by law and assume all of
Company's obligations under the Business Management Agreement.

any of their respective former employees who have retired except as may be
required pursuant to the continuation of coverage provisions of Section 4980B of
the Code and Sections 501 through 508 of ERISA.

Partnership owns any interest (other than leasehold interests referred to on

True, correct and complete copies of the written Commitments, and true, correct
and complete written descriptions of the oral Commitments, have heretofore been
delivered or made available to Vision 21. Except as set forth on Schedule 3.15
and to the Company's best knowledge, there are no existing or asserted defaults,
events of default or events, occurrences, acts or omissions that, with the
giving of notice or lapse of time or both, would constitute defaults by the
Company or the Partnership or, to the best knowledge of the Company, any other
party to a material Commitment, and no penalties have been incurred nor are
amendments pending, with respect to the material Commitments, except as
described on Schedule 3.15. The Commitments are in full force and effect and are
valid and enforceable obligations of the Company or the Partnership, and to the
best knowledge of the Company, are valid and enforceable obligations of the
other parties thereto, in accordance with their respective terms, and no
defenses, off-sets or counterclaims have been asserted or, to the best knowledge
of the Company, may be made by any party thereto (other than the Company or the
Partnership), nor have the Company or the Partnership waived any rights
thereunder, except as described on Schedule 3.15. Except as set forth on
Schedule 3.15, no consents or approvals are required under the terms of any
agreement listed on Schedule 3.15 in connection with the transactions
contemplated herein; including without limitation the Merger.

                  b.       No Cancellation or Termination of Commitment. Except
as disclosed pursuant to this Agreement or contemplated hereby, and except where
such default would not have a Material Adverse Effect on the business, (i) none
of the Company, the Partnership or the Physician has received notice of any plan
or intention of any other party to any Commitment to exercise any right to
cancel or terminate any Commitment, and the Company does not know of any fact
that would justify the exercise of such a right; and (ii) none of the Company,
the Partnership or the Physician currently contemplates, or has reason to
believe any other person currently contemplates, any amendment or change to any
Commitment.

<PAGE>   22

Partnership, the Physician and each Professional Employee relating to the
respective businesses of the Company and the Partnership and the Nonmedical
Assets. All of the Insurance Policies are issued by insurers of recognized
responsibility, and, to the best knowledge of the Company, are valid and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies. All Insurance Policies shall be maintained
in force without interruption up to and including the Closing Date. True,
complete and correct copies of all Insurance Policies have been provided or made
available to Vision 21. Except as set forth on Schedule 3.16, none of the
Company, the Partnership or the Physician has received any notice or other
communication from any issuer of any Insurance Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, and to the
actual knowledge of the Company, no such cancellation or increase of
deductibles, retainages or premiums is threatened. Except as set forth on
Schedule 3.16, none of the Company, the Partnership, the Physician or any
Professional Employee has any outstanding claims, settlements or premiums owed
against any Insurance Policy, and the Company, the Partnership, the Physician
and each Professional Employee has given all notices or have presented all

written application for any professional liability insurance coverage which has
been denied by an insurance agency or carrier, and the Company, the Partnership,
the Physician and each Professional Employee have been continuously insured for
professional malpractice claims for at least the past seven (7) years (or such
shorter periods of time that any Professional Employee has been licensed to
practice medicine). Schedule 3.16 also sets forth a list of all claims under any
Insurance Policy in excess of $10,000 per occurrence filed by the Company, the

trade designations, including common law rights, registrations and applications
therefor, and all patents and applications therefor currently owned, in whole or
in part, by the Company or the Partnership and all licenses, royalties,

either the Company or the Partnership is a party (including the expiration date
thereof if applicable); and

                  b.       all agreements relating to technology, know-how or
processes that the Company or the Partnership has licensed or authorized to use

other health care providers), or which either the Company or the Partnership
licenses or authorizes others to use.

The Company and/or the Partnership own or have the legal right to use the
Proprietary Rights, and to the knowledge of the Company, such ownership or use
does not conflict, infringe or violate the rights of any other person. Except as
disclosed on Schedule 3.17, no consent of any person will be



                                      -22-

required for the use thereof by Vision 21 upon consummation of the transactions
contemplated hereby and the Proprietary Rights are freely transferable. No claim
has been asserted by any person to the ownership of or for infringement by the
Company or the Partnership of the proprietary right of any other person, and the
Company does not know of any valid basis for any such claim. To the best
knowledge of the Company and the Physician, the Company and the Partnership have
the right to use, free and clear of any adverse claims or rights of others, all
trade secrets, customer lists and proprietary information required for the
marketing of all merchandise and services formerly or presently sold or marketed

assessment, proposal for additional taxes, deficiency or delinquency in the
payment of any of the taxes of the Company or the Partnership that could be

the Physician or any Professional Employee to comply with all applicable laws,
regulations and licensing requirements relating to the operation of the Practice

of this Agreement, will be validly issued, fully paid and nonassessable and will
not have been issued in violation of any preemptive rights, rights of first
refusal or similar rights of any of Vision 21's stockholders, or any federal or
state law, including, without limitation, the registration requirements of
applicable federal and state securities laws.

         5.9.     Continuity of Business Enterprise. It is the present intention
of Vision 21 to continue at least one significant historic business line of the
Company, or to use at least a significant portion of the Company's historic
business assets in a business, in each case within the meaning of Treasury
Regulation Section 1.368-1(d).

         5.10.    Vision 21 Financial Statements. The audited consolidated
balance sheet and related statements of income and cash flows of Vision 21 for
its prior three (3) full fiscal years, and its unaudited interim balance sheet
for the six (6) month period ended June 30, 1997, and the related unaudited
statement of income of Vision 21 for the period then ended (collectively, with
the related notes thereto, the "Vision 21 Financial Statements"), (a) fairly
present the financial condition and results of operations of Vision 21 as of the
dates and for the periods indicated; and (b) have been prepared in conformity
with GAAP (subject to normal year-end adjustments and the absence of notes for
any unaudited interim financial statement), except as otherwise indicated in the
Vision 21 Financial Statements.

         5.11.    Liabilities and Obligations. Except as disclosed on Schedule
5.11, the Vision 21 Financial Statements shall reflect all material liabilities
of Vision 21, accrued, contingent or otherwise, that would be required to be
reflected on a balance sheet, or in the notes thereto, prepared in accordance
with GAAP. Except as set forth on Schedule 5.11 or in the Vision 21 Financial
Statements, Vision 21 is not liable upon or with respect to, or obligated in any
other way to provide funds in respect of or to guarantee or assume in any
manner, any debt, obligation or dividend of any person, corporation,
association, partnership, joint venture, trust or other entity, and Vision 21
does not know of any valid basis for the assertion of any other claims or
liabilities of any nature or in any amount.

         5.12.    Compliance with Laws. Vision 21 has not failed to comply with
any applicable laws, regulations and licensing requirements or failed to file
with the proper authorities any necessary statements and reports except where
the failure to so comply or file would not, individually or in the aggregate,
have a material adverse effect on the Merger. There are no existing violations
by Vision 21 of any federal, state or local law or regulation that could,
individually or in the aggregate, have a material adverse effect on the Merger.
Vision 21 possesses all necessary licenses, franchises, permits and governmental
authorizations for the conduct of Vision 21's business as now conducted and
after the Closing, as contemplated in this Agreement and the Business Management
Agreement, except for such licenses, franchises, permits or governmental
authorizations which, if not possessed by Vision 21, would not have a material
adverse effect on the business of Vision 21. The transactions contemplated by
this Agreement will not result in a default under or a breach or



                                      -35-
<PAGE>   36

violation of, or adversely affect the rights and benefits afforded by any such
licenses, franchises, permits or government authorizations, except for any such
default, breach or violation that would not, individually or in the aggregate,
have a material adverse effect on the Merger or the performance of the services
contemplated under the Business Management Agreement. Since January 1, 1993,
Vision 21 has not received any notice from any federal, state or other
governmental authority or agency having jurisdiction over its properties or
activities, or any insurance or inspection body, that its operations or any of
its properties, facilities, equipment, or business practices fail to comply with
any applicable law, ordinance, regulation, building or zoning law, or
requirement of any public or quasi-public authority or body, except where
failure to so comply would not, individually or in the aggregate, have a
material adverse effect on the Merger.

         5.13.    Insolvency Proceedings. Vision 21 is not currently under the
jurisdiction of a Federal or state court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

         5.14.    Equal Exchange. Vision 21 believes that the fair market value
of all the Company Common Stock shall be approximately equal to the fair market
value of the Merger Consideration at the Effective Time.

         5.15.    Employment of Company's Employees. Vision 21 does not
currently intend to change the existing composition or employment terms of any
of the non-professional personnel which have employment arrangements with the
Company or the Partnership on the effective date of this Agreement (except as is
necessary for Vision 21 to employ such individuals pursuant to the Business
Management Agreement). Vision 21 reserves the right, however, to change the
number, composition or employment terms of such non-professional personnel in
the future.

         6.       CLOSING DATE REPRESENTATIONS AND WARRANTIES OF THE
PHYSICIAN. The Physician represents and warrants that, except as disclosed in
the Schedules, the following will be true and correct on the Closing Date as if

carry on the business in which it intends to engage, to own the properties it
intends to own, and to execute and deliver the Business Management Agreement and
the Physician Employment Agreements and consummate the transactions and perform
the services contemplated thereby. New P.A. is duly qualified and licensed to do

issued and outstanding, and no shares of capital stock of New P.A. are held in

<PAGE>   37

of all security interests, liens, adverse claims, encumbrances, equities,
proxies and shareholders' agreements, and Physician owns _____ of such shares of
New P.A. common stock. Each outstanding share of New P.A.'s common stock has
been legally and validly issued and is fully paid and nonassessable. There exist
no options, warrants, subscriptions or other rights to purchase, or securities
convertible into or exchangeable for, any of the authorized or outstanding

or disposed of in violation of the preemptive rights, rights of first refusal or
similar rights of any of New P.A.'s stockholders.

         6.3.     Corporate Records. The copies of the Articles or Certificate
of Incorporation and Bylaws, and all amendments thereto, of New P.A. that have

without meetings by, the Board of Directors (and any committees thereof) and the
stockholders of New P.A. since its formation.

         6.4.     Authorization and Validity. The execution, delivery and
performance by New P.A. of the Business Management Agreement, the Physician
Employment Agreements, the Optometrist Employment Agreements and the other

P.A. The Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements and each other agreement contemplated thereby
will be as of the Closing Date duly executed and delivered by New P.A. and will
constitute legal, valid and binding obligations of New P.A. enforceable against
New P.A. in accordance with their respective terms, except as may be limited by
applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally or the availability of equitable remedies.

         6.5.     No Violation. Neither the execution, delivery or performance
of the Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements or the other agreements contemplated thereby
nor the consummation of the transactions or provision of services contemplated
thereby will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the Articles or
Certificate of Incorporation or Bylaws of New P.A., or (b) to the actual
knowledge of the Physician, violate or conflict with any judgment, decree,
order, statute, rule or regulation of any court or any public, governmental or
regulatory agency or body.

         6.6.     No Business, Agreements, Assets or Liabilities. New P.A. has
not commenced business since its incorporation. Other than its Articles or

other than the consideration received upon the issuance of shares of capital
stock and New P.A. does not have any liabilities, accrued, contingent or
otherwise (known or unknown and asserted or unasserted).

         6.7.     Compliance with Laws. New P.A. has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure to
so comply or file would not, individually or in the aggregate, have a material
adverse effect on the business, operations or financial condition of New P.A.

         7.       SECURITIES LAW MATTERS.

         7.1.     Investment Representations and Covenants of Physician.

                  a.       Physician understands that the Securities will not be
registered under the Securities Act or any state securities laws on the grounds
that the issuance of the Securities is exempt from registration pursuant to
Section 4(2) of the Securities Act under the Securities Act and applicable state
securities laws, and that the reliance of Vision 21 on such exemptions is
predicated in part on the Physician's representations, warranties, covenants and
acknowledgements set forth in this Section.

                  b.       Except as disclosed on Schedule 7.1(b) attached
hereto, Physician represents and warrants that Physician is an "accredited
investor" or "sophisticated investor" as defined under the Securities Act and
state "Blue Sky" laws, or that Physician has utilized, to the extent necessary
to be deemed a sophisticated investor under the Securities Act and State "Blue
Sky" laws, the assistance of a professional advisor.

                  c.       Physician represents and warrants that the Securities
to be acquired by Physician upon consummation of the transactions described in
this Agreement will be acquired by Physician for Physician's own account, not as
a nominee or agent, and without a view to resale or other distribution within
the meaning of the Securities Act and the rules and regulations thereunder,
except as contemplated in this Agreement, and that Physician will not distribute
any of the Securities in violation of the Securities Act. All Securities shall
bear a restrictive legend in substantially the following form:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE
         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

         In addition, the Securities shall bear any legend required by the
securities or "Blue Sky" laws of any state where Physician resides as well as
any other legend deemed appropriate by Vision 21 or its counsel.



                                      -38-
<PAGE>   39

                  d.       Physician represents and warrants that the address
set forth below Physician's name on Schedule 7.1(d) is Physician's principal
residence.

                  e.       Physician (i) acknowledges that the Securities issued
to Physician at the Closing must be held indefinitely by Physician unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that in
such cases where the Rule is not applicable, compliance with some other
registration exemption will be required, and (iii) is aware that Rule 144 is not
currently available for use by Physician for resale of any of the Securities to
be acquired by Physician upon consummation of the transactions described in this
Agreement.

                  f.       Physician represents and warrants to Vision 21 that
Physician, either alone or together with the assistance of Physician's own
professional advisor, has such knowledge and experience in financial and
business matters such that Physician is capable of evaluating the merits and
risks of Physician's investment in any of the Securities to be acquired by
Physician upon consummation of the transactions described in this Agreement.

                  g.       Physician confirms that Physician has had the
opportunity to ask questions of and receive answers from Vision 21 concerning
the terms and conditions of Physician's investment in the Securities, and the
Physician has received to Physician's satisfaction, such additional information,
in addition to that set forth herein, about Vision 21's operations and the terms
and conditions of the offering as Physician has requested.

                  h.       In order to ensure compliance with the provisions of
paragraph (c) hereof, Physician agrees that after the Closing Physician will not
sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the Securities Act) without first
complying with either of the following conditions, the expenses and costs of
satisfaction of which shall be fully borne and paid for by Physician:

                           i)       Vision 21 shall have received a written
legal opinion from legal counsel, which opinion and counsel shall be
satisfactory to Vision 21 in the exercise of its reasonable judgment, or a copy
of a "no-action" or interpretive letter of the Securities and Exchange
Commission specifying the nature and circumstances of the proposed transfer and
indicating that the proposed transfer will not be in violation of any of the
registration provisions of the Securities Act and the rules and regulations
promulgated thereunder; or

                           ii)      Vision 21 shall have received an opinion
from its own counsel to the effect that the proposed transfer will not be in
violation of any of the registration provisions of the Securities Act and the
rules and regulations promulgated thereunder.



                                      -39-
<PAGE>   40

Physician also agrees that the certificates or instruments representing the
Securities to be issued to Physician pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this Section
and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 7.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.

                  i.       Physician understands that there can be no assurance
that a Public Offering by Vision 21 will ever occur or if it does occur that it
will be successful.

                  j.       Physician agrees that he shall be considered an
"affiliate" of Vision 21 for purposes of Rule 144 and agrees to the restrictions
and limitations imposed by Rule 144 on affiliates. Physician further agrees that
he shall be considered an affiliate of Vision 21 for Rule 144 purposes even if
he does not meet the technical definition of "affiliate" under Rule 144.

         7.2.     Current Public Information. At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act, as
such Rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC) regarding the availability of current public
information to the extent required to enable any holder of shares of Common
Stock to sell such shares without registration under the Securities Act pursuant
to Rule 144 (or any similar rule or regulation).

         8.       COVENANTS OF THE COMPANY AND THE PHYSICIAN. The Company and
the Physician, jointly and severally, agree that between the date hereof and the

Partnership and the Physician shall cause, at or immediately prior to Closing,
each Optometrist Employee (except for those Optometrist Employees identified on
Schedule 8.17) who is then an employee of the Company (i) to terminate his
employment agreement, if any, with the Company or the Partnership by mutual
consent without any liability therefor on the part of the Company, and (ii) to
enter into a new Optometrist Employment Agreement with New P.A. in accordance
with the Business Management Agreement.

         8.18.    Termination of Retirement Plans. Prior to Closing, the
Physician shall cause the Company (and the Company shall cause the Partnership)
to take all steps necessary to discontinue benefits accruals under any Employee
Benefit Plan that is intended to be a qualified employee retirement plan under
Section 401(a) of the Code (a "Retirement Plan") effective as of Closing or as
soon thereafter as may be practical. Effective at the time of Closing, the
Company and the Partnership shall cause New P.A. to assume all of the
obligations of the Company and the Partnership as the sponsoring employer and/or
plan administrator of the Retirement Plan in compliance with applicable law.

         Subsequent to Closing, New P.A. and Vision 21 shall review the extent
to which New P.A. can resume contributions to the Retirement Plan without
violating the qualification requirements of



                                      -44-
<PAGE>   45

Sections 410(b) and 401(a)(4) of the Code taking into account any employees of
Vision 21 who would be "leased employees" of New P.A. under Section 414(n) of
the Code. If Vision 21 and New P.A. mutually agree that such qualification
requirements can be satisfied, New P.A. may elect to continue the Retirement
Plan and make contributions in accordance with its terms, provided that New P.A.
shall agree to cover at its own expense any Vision 21 employees who are leased
employees if such coverage is required to maintain the tax-qualified status of
the Retirement Plan.

         8.19.    Delivery of Schedules. The Company and the Physician shall
deliver to Vision 21 all Schedules required to be delivered by them prior to the
Closing.

         8.20.    Conversion of Company. After the transfer of the Medical
Assets of the Company and the Partnership to New P.A. and the assumption of the
Excluded Liabilities by New P.A. and prior to Closing, Physician shall cause the
Company to take such action and file such documents or instruments as may be
necessary to convert the Company into a general business corporation in
accordance with applicable law.

         8.21.    Assignment of Fees for Medical and Optometry Services. On or
prior to the Closing Date, the Company shall obtain an irrevocable assignment
from all Professional Employees of any and all of their rights to receive
payment for the provision of ophthalmology or optometry services which are part
of the Accounts Receivable to the Company existing on the Closing Date, except
for those fees specified and set forth on Schedule 8.21. Each Professional
Employee shall undertake to endorse any payments received on account of such
services to the order of the Company and to take such other action as may be
necessary to confirm to the Company the rights to collect and retain for its own
account such Accounts Receivable. The Company shall cause its Professional
Employees to agree that such security interest of such lender(s) is intended to
be a first priority security interest and is superior to any right, title or
interest which may be asserted by such Professional Employees with respect to
the Accounts Receivable or the proceeds thereof. In the event that the
assignment of rights described in this Section shall be deemed, for any reason,
to be ineffective as an outright assignment, the Company shall cause each
Professional Employee to agree that such Professional Employee shall be deemed,
effective as of the Closing Date, to have granted to the Company a first
priority lien on and security interest in and to any and all interests of such
Professional Employee in any of the Accounts Receivable, and all proceeds with
respect thereto, to secure the collection by the Company of all Accounts
Receivable, and this Agreement shall be deemed to be a security agreement to the
extent necessary to give effect to the foregoing. The Company shall cause each
Professional Employee to execute and deliver, all such financing statements as
the Company or Vision 21 may request in order to perfect such security interest.
The Company shall not suffer any Professional Employee to grant any other lien
on or security interest in or to such Accounts Receivable or any proceeds
thereof.

         9.       COVENANTS OF VISION 21. Vision 21 agrees that between the date
hereof and the Closing:

         9.1.     Consummation of Agreement. Vision 21 shall use its best
efforts to cause the consummation of the transactions contemplated hereby in

actions necessary to approve the Merger; provided, however, that this covenant

forth in this Agreement or otherwise contemplated herein.

         9.2.     Efforts to Effect. Vision 21 will use its best efforts to
take, or cause to be taken, all actions necessary to effect the Merger under

government officials of all necessary documents in form approved by counsel for
the parties to this Agreement.

inform the Company and the Physician in writing of (a) any notice of, or other
communication relating to, a default or event that, with notice or lapse of time

this Agreement and prior to the Effective Time under any agreement or commitment
entered into by Vision 21 material to Vision 21's condition (financial or

or otherwise), operations, assets, liabilities or business.

obtain all licenses, permits, approvals or other authorizations required under
any law, statute, rule, regulation or ordinance, or otherwise necessary or
desirable to consummate the transactions or provide the services contemplated by
the Business Management Agreement and to conduct the intended business of Vision
21.

         9.6.     Release of Physician From Practice Liabilities. Vision 21
shall use its best efforts to obtain from third party creditors the release of
Physician from any personal liabilities relating to the Practice which are
identified on Schedule 9.6 and assumed by Vision 21 pursuant to the terms of
this Agreement.

         10.      COVENANTS OF VISION 21, THE COMPANY AND THE PHYSICIAN. Vision
21, the Company and the Physician agree as follows (with respect to New P.A.'s
covenants, the Physician agrees to cause New P.A. to perform and with respect to
the Partnership's covenants, the Company agrees to use its best efforts to cause
the Partnership to perform):

         10.1.    Amendment of Schedules. Each party hereto agrees that, with

<PAGE>   47

respect to any matter that would have been or would be required to be set forth
or described in the Schedules in order to not materially breach any
representation, warranty or covenant of such party contained herein; provided
that no amendment or supplement to a Schedule that constitutes or reflects a
material adverse change to the Company, the Partnership or the Nonmedical Assets
may be made unless Vision 21 consents to such amendment or supplement, and no
amendment or supplement to a Schedule that constitutes or reflects a material
adverse change to Vision 21 may be made unless the Company and the Physician
consent to such amendment or supplement. For all purposes of this Agreement,
including without limitation for purposes of determining whether the conditions
set forth in Sections 11.1 and 12.1 have been fulfilled, the Schedules hereto
shall be deemed to be the Schedules as amended or supplemented pursuant to this
Section 10.1. In the event that the Company is required to amend or supplement a
Schedule in accordance with this Section 10.1 and Vision 21 does not consent to
such amendment or supplement, or Vision 21 is required to amend or supplement a
Schedule in accordance with this Section 10.1 and the Company and the Physician
do not consent, this Agreement shall be deemed terminated by mutual consent as
set forth in Section 16.1(d) or Section 16.1(e) as appropriate.

         10.2.    Business Management Agreement. The Company and the Physician
shall use their best efforts to cause the Business Management Agreement to be

21 in the Merger.

however, that the Company may utilize the Prepared Audit Materials solely in
connection with its review of Vision 21's calculation of the Merger
Consideration. The Prepared Audit Materials shall not be deemed to include those
items which customarily remain the property of auditors such as their working
papers and memos.

                  b.       In the event the Merger is not consummated, Vision

council composed of delegates from Vision 21 and New P.A. which shall advise
Vision 21 and New P.A. and determine certain issues as more fully described in
the Business Management Agreement. Vision 21 shall also establish a local
advisory council composed of delegates from certain practice groups acquired by
Vision 21 in connection with Recent Acquisitions, delegates from the Company and
delegates from Vision 21. Such delegates shall be appointed from practice groups
which are located in a market area to be identified by Vision 21 and in which
New P.A. is located. The local advisory council board shall advise Vision 21 and
the practice groups within the market area as to policy and strategy issues and
shall determine certain types of issues and disputes between Vision 21 and such
practice groups which issues and disputes are identified in the Business
Management Agreement and other management agreements entered into between Vision
21 and practice groups. New P.A. shall have the right to appoint one (1) member
to a local advisory council who shall serve an initial two (2) year term. After
the initial two-year term, election of members to the local advisory council
shall be in accordance with by-laws which shall be adopted and amended by the
local advisory council. Vision 21 shall also establish a national appeals
council which shall have, among other duties and responsibilities, the power to
adopt and amend its by-laws, to review and approve as limited herein certain
decisions of the local advisory councils, and to resolve deadlocks among the
members of such local advisory councils.

         14.3.    Restrictions on Transfer of Vision 21 Common Stock. Physician
shall not dispose of any of the Vision 21 Common Stock received in the Merger
(including any Vision 21 Common Stock received by the Company as contingent
consideration in connection with the Merger) within two (2) years of the
Effective Time of the Merger if such disposition would reduce the fair value of
the Vision 21 Common Stock (with such fair value measured as of the Effective
Time of the Merger) retained by the Physician to an amount less than fifty
percent (50%) of (a) the fair value of the Company Common Stock held by the
Physician immediately before the Effective Time of the Merger, plus (b) the
value of any contingent consideration received by the Company in connection with
the Merger, unless the Physician obtains an opinion of counsel reasonably
satisfactory to Vision 21 that such transfer will not violate the continuity of
shareholder interest requirement set forth in Treas. Reg. ss.1.388-1. In the
event that Physician wishes to dispose of any shares of Vision 21 Common Stock
received in the Merger within such two (2) year period, Physician shall provide
written notice to Vision 21, not less than ten (10) days prior to the intended
date of disposition, specifying the number of shares of which the Physician
proposes to dispose.

         14.4.    Access to Books and Records. From and after the Closing Date,
at the request of any party hereto, each of the other parties shall reasonably
cooperate in providing the requesting party with access to such other parties'
personnel who are knowledgeable concerning, and books and records which are
relevant to, the inquiry by the requesting party; provided, however, that (a)
such personnel shall be available at, and the access to such books and records
shall be granted at the responding party's business premises and during the
responding party's regular business hours, and (b) the inquiry shall be for a
legitimate business purpose, including tax filings and compliance,



                                      -54-
<PAGE>   55

defending against litigation or other claims, or for any other legitimate
business purpose. All copies of such books and records shall be at the
requesting party's expense. Each of the parties to this Agreement shall retain
all books and records with respect to the transactions contemplated herein for a
minimum of five (5) years from the Closing Date.

         15.      REMEDIES.

         15.1.    Indemnification by the Physician. Subject to the terms and
conditions of this Agreement, the Physician agrees to indemnify, defend and hold
Vision 21, the Surviving Corporation and their respective directors, officers,
employees, agents, attorneys and affiliates harmless from and against all
losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (collectively,
"Damages") asserted against or incurred by such entities and individuals
(including, but not limited to, any reduction in payments to or revenues of New

of the Company or the Physician contained herein or in any schedule or
certificate delivered hereunder;

                  b.       any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, (i) arising out of or based upon any untrue statement
or alleged untrue statement of a material fact relating to the Physician, the
Company (including its subsidiaries, if any), the Partnership or New P.A., and
provided to Vision 21 or its counsel by the Company or the Physician,
specifically for inclusion in a Registration Statement or any prospectus forming
a part thereof, or any amendment thereof or supplement thereto, (ii) arising out
of or based upon any omission or alleged omission to state therein a material
fact relating to the Physician, the Company (including its subsidiaries, if
any), the Partnership or New P.A. required to be stated therein or necessary to
make the statements therein not misleading, and not provided to Vision 21 or its
counsel by the Company or the Physician, provided, however, that such indemnity
shall not inure to the benefit of Vision 21 to the extent that such untrue
statement (or alleged untrue statement) was made, in, or omission (or alleged
omission) occurred in, any preliminary prospectus, and such information was not
so included by Vision 21 and properly delivered to shareholders of Vision 21 who
acquire Vision 21 Common Stock in any Public Offering;

                  c.       any filings, reports or disclosures made pursuant to
the IRS Voluntary Compliance Resolution Program, if applicable;

                  d.       any failure of the Merger to qualify as a
reorganization within the meaning of Section 368(a)(1)(A) or Section
368(a)(2)(D) of the Code;

                  e.       any liability arising from the spin off of the
Company's medical business and Medical Assets;


                                      -55-
<PAGE>   56


                  f.       any and all liability for any actions, suits, claims,
proceedings or investigations that relate to Physician, the Company or the
Partnership in which the event giving rise thereto occurred prior to the Closing
Date or which result from or arise out of any action of Physician or any
partner, director, officer, employee, agent or representative of the Partnership
or the Company prior to the Closing Date;

                  g.       any liability of Physician, the Company or the
Partnership of any nature whatsoever not disclosed in this Agreement and
expressly assumed by Vision 21; and

                  h.       any liability arising from any alleged unlawful sale
or offer to sell or transfer any of the Common Stock by Physician.

         15.2.    Indemnification by Vision 21. Subject to the terms and
conditions of this Agreement, Vision 21 hereby agrees to indemnify, defend and
hold the Physician harmless from and against all damages asserted against or
incurred by him arising out of or resulting from:

                  a.       a breach by Vision 21 of any representation, warranty
or covenant of Vision 21 contained therein or in any schedule or certificate
delivered hereunder;

                  b.       any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to Vision 21, contained in
any preliminary prospectus, Registration Statement or any prospectus forming a
part thereof, or any amendment thereof or supplement thereto, arising out of or
based upon any omission or alleged omission to state therein a material fact
relating to Vision 21 (including its subsidiaries), required to be stated
therein or necessary to make the statements therein not misleading; and

                  c.       any filings, reports or disclosures made pursuant to
the IRS Voluntary Compliance Resolution Program, if applicable.

         Notwithstanding anything in this Section 15.2, Vision 21 shall not be
liable for any Damages resulting from any matter not disclosed to Vision 21 by
any of the third parties acquired by Vision 21 in connection with Recent
Acquisitions.

         15.3.    Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                  a.       A party claiming indemnification under this Agreement
(an "Indemnified Party") shall promptly (and, in any event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party from whom indemnification is sought (the
"Indemnifying Party") of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this



                                      -56-
<PAGE>   57

Agreement and (ii) transmit to the Indemnifying Party a written notice ("Claim
Notice") describing in reasonable detail the nature of the Third Party Claim, a
copy of all papers served with respect to such claim (if any), an estimate of
the amount of damages attributable to the Third Party Claim and the basis of the
Indemnified Party's request for indemnification under this Agreement. Except as
set forth in Section 15.6, the failure to promptly deliver a Claim Notice shall
not relieve the Indemnifying Party of its obligations to the Indemnified Party
with respect to the related Third Party Claim except to the extent that the
resulting delay is materially prejudicial to the defense of such claim. Within
thirty (30) days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Party shall notify the Indemnified Party (i) whether the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 15 with respect to such Third Party Claim and (ii) whether
the Indemnifying Party desires, at the sole cost and expense of the Indemnifying
Party, to defend the Indemnified Party against such Third Party Claim.

                  If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 15.3(b). The Indemnifying
Party shall have full control of such defense and proceedings, including any
compromise or settlement thereof. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is entitled to indemnification hereunder), to file, during the Election
Period, any motion, answer or other pleadings that the Indemnified Party shall
deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being
understood and agreed that if an Indemnified Party takes any such action that is
prejudicial and causes a final adjudication that is adverse to the Indemnifying
Party, the Indemnifying Party shall be relieved of its obligations hereunder
with respect to such Third Party Claim). If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to
Section 15.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or 



                                      -57-
<PAGE>   58

circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys at any time for the Indemnified Party, which firm
shall be designated in writing by the Indemnified Party.

                  b.       If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 15.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
15.3(b) but fails diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party (if the Indemnified Party is entitled
to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 15 and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnifying Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party
in full for all costs and expenses of such litigation. The Indemnifying Party
may participate in, but not control any defense or settlement controlled by the
Indemnified Party pursuant to this Section 15.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

                  c.       In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 19.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.



                                      -58-
<PAGE>   59

                  d.       Payments of all amounts owing by an Indemnifying
Party pursuant to this Article 15 relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim or (iii) the expiration of the period for
appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by an
Indemnifying Party pursuant to Section 15.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the sixty (60) day Indemnity
Notice period or (ii) the expiration of the period for appeal, if any, of a
final adjudication or arbitration of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

         15.4.    Remedies Not Exclusive. The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity. This Article 15
regarding indemnification shall survive Closing.

         15.5.    Costs, Expenses and Legal Fees. Each party hereto agrees to
pay the costs and expenses (including attorneys' fees and expenses) incurred by
the other parties in successfully (a) enforcing any of the terms of this
Agreement, or (b) proving that another party breached any of the terms of this
Agreement.

         15.6.    Indemnification Limitations. Notwithstanding the provisions of
Sections 15.1 and 15.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2, 3.3., 3.4, 3.5,
3.6, 3.14, 3.17, 3.20, 3.23, 4.1, 4.3, 4.4, 4.8, 5.1, 5.2, 5.3, 5.4, 5.6, 5.7,
6.1, 6.2, 6.3 and 6.4 may be made at any time, and a claim for indemnification
for a breach of the representations and warranties contained in Sections 3.12,
3.18, 3.21, 3.27, 3.28, 3.29, 3.30, 3.31, 3.33, 4.5, 4.7, 4.10, 5.8 and 7.1 may
be made at any time within the applicable statute of limitations; (b)
indemnification based upon Sections 15.1(b) through (f) and 15.2(b) may be made
at any time within the applicable statute of limitations; and (c) the Physician
shall not be required to indemnify Vision 21 pursuant to Section 15.1 unless,
and to the extent that, the aggregate amount of Damages incurred by Vision 21
shall exceed an amount equal to two percent (2%) of the total Merger
Consideration; and (d) the Physician shall not be required to indemnify Vision
21 with respect to a breach of a representation, warranty or covenant for
Damages in excess of the aggregate Merger Consideration received by the
Physician (other than pursuant to a requirement to indemnify Vision 21 under
Sections 3.30 and 3.31, or unless the breach involves an intentional breach or
fraud by the Physician, which shall be unlimited).

         15.7.    Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds and such correlative insurance
benefit shall be net of the insurance premium, if any, that becomes due as a
result of such claim.



                                      -59-
<PAGE>   60

         15.8.    Payment of Indemnification Obligation. In the event that the
Physician has an indemnification obligation to Vision 21 hereunder, subject to
Vision 21's approval as set forth below, the Physician may satisfy such
obligation by transferring to Vision 21 such number of shares of Vision 21
Common Stock owned by the Physician having an aggregate fair market value (which
is the fair market value at such time based on the last reported sale price of
Vision 21 Common Stock on a principal national securities exchange or other
exchange on which the Vision 21 Common Stock is then listed or the last quoted
ask price on any over-the-counter market through which the Vision 21 Common
Stock is then quoted on the last trading day immediately preceding the day on
which the Physician transfers shares of Vision 21 Common Stock to Vision 21
hereunder) equal to the indemnification obligation, provided that each of the
following conditions are satisfied:

                  a.       The Physician shall transfer to Vision 21 good, valid
and marketable title to the shares of Vision 21 Common Stock, free and clear of
all adverse claims, security interests, liens, claims, proxies, options,
stockholders' agreements and encumbrances;

                  b.       The Physician shall make such representation and
warranties as to title to the stock, absences of security interests, liens,
claims, proxies, stockholders' agreements and other encumbrances and other
matters as reasonably requested by Vision 21; and

                  c.       The other terms and conditions of any transaction
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21.

         16.      TERMINATION.

         16.1.    Termination. This Agreement may be terminated and the Merger
may be abandoned:

                  a.       at any time prior to the Closing Date by mutual
agreement of all parties;

                  b.       at any time prior to the Closing Date by Vision 21 if
any representation or warranty of the Company or the Physician contained in this
Agreement or in any certificate or other document executed and delivered by the
Company or the Physician pursuant to this Agreement is or becomes untrue or
breached in any material respect or if the Company or the Physician fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt of written notice thereof;

                  c.       at any time prior to the Closing Date by the Company
if any representation or warranty of Vision 21 contained in this Agreement is or
becomes untrue in any material respect or if Vision 21 fails to comply in any
material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt or written notice thereof;



                                      -60-
<PAGE>   61

                  d.       at any time prior to the Closing Date by the Company
in the event of the failure of any of the conditions precedent set forth in
Article 13 of this Agreement;

                  e.       at any time prior to the Closing Date by Vision 21 in
the event of the failure of any of the conditions precedent set forth in Article
12 of this Agreement;

                  f.       by Vision 21 if at any time prior to the Closing
Date, Vision 21 deems termination to be advisable, provided, however, that if
Vision 21 exercises its right to terminate this Agreement under this subsection,
Vision 21 shall reimburse the Company and the Physician for all reasonable
attorneys' and accountants' fees incurred by the Company and the Physician in
connection with this Agreement; provided that Vision 21 shall only reimburse the
Company and the Physician up to an aggregate maximum amount of One Hundred
Thousand and No/100 Dollars ($100,000.00) for such fees; or

                  g.       by Vision 21 or the Company if the Merger shall not
have been consummated by November 30, 1997.

         16.2.    Effect of Termination. In the event this Agreement is
terminated pursuant to Section 16.1, Vision 21, the Company and the Physician,
shall each be entitled to pursue, exercise and enforce any and all remedies,
rights, powers and privileges available at law or in equity, subject to the
limitations set forth in Section 15.1. In the event of a termination of this
Agreement under the provisions of this Article 16, a party not then in material
breach of this Agreement shall stand fully released and discharged of any and
all obligations under this Agreement.

         17.      PHYSICIAN EMPLOYMENT AGREEMENT.

         17.1.    Physician Employment Agreement. The parties acknowledge that
in accordance with the terms of this Agreement, Physician, as employee, and New
P.A., as employer, have entered into the Physician Employment Agreement and that
Vision 21 is entitled to enforce such Physician Employment Agreement as an
intended third party beneficiary. Physician and Vision 21 acknowledge that
Vision 21 would suffer severe harm in the event of Physician's resignation prior
to the expiration of the five (5) year term of such Physician Employment
Agreement (without first obtaining the written consent of Vision 21) or a breach
or default of Physician's obligations under such Physician Employment Agreement,
and Physician, the Company and Vision 21 agree that Vision 21 shall be entitled
to recover from Physician any and all damages incurred by Vision 21 caused by
such resignation, breach or default. Notwithstanding the foregoing, Vision 21
shall not be entitled to recover its damages caused by such resignation, breach
or default if such resignation, breach or default was caused by: (i) the death
or disability of Physician, (ii) circumstances not caused by an act or omission
of Physician and which circumstances are beyond his control, or (iii) loss of
Physician's license to practice as an ophthalmologist, unless such loss of
license is due to an act or omission of Physician. Notwithstanding the
foregoing, Physician shall have no obligation to pay the damages contemplated in
this Section 17.1 if (a) the Business Management Agreement has



                                      -61-
<PAGE>   62

been terminated pursuant to a material breach by Vision 21, or (b) Physician
cures any such breach or default of the Physician Employment Agreement within a
period of thirty (30) days after notice from Vision 21 of such breach or
default.

         17.2.    Survival. The parties acknowledge and agree that this Article
17 shall survive the Closing of the transactions contemplated herein.

         18.      NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

         18.1.    Physician Non-Competition Covenant.

                  a.       The Physician recognizes that the covenants of the
Physician contained in this Section 18.1 are an essential part of this Agreement
and that, but for the agreement of the Physician to comply with such covenants,
Vision 21 would not have entered into this Agreement. The Physician acknowledges
and agrees that the Physician's covenant not to compete is necessary to ensure
the continuation of the Management Business (as defined below) and is necessary
to protect the reputation of Vision 21, and that irreparable and irrevocable
harm and damage will be done to Vision 21 if the Physician competes with the
Management Business or Vision 21. The Physician accordingly agrees that for the
periods set forth in the Business Management Agreement, the Physician shall not:

                           i)       directly or indirectly, either as principal,
agent, independent contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's own benefit or
for the benefit of any other person or entity knowingly (A) hire, attempt to
hire, contact or solicit with respect to hiring any employee of Vision 21 (or of
any of its direct or indirect subsidiaries) or (B) induce or otherwise counsel,
advise or encourage any employee of Vision 21 (or of any of its direct or
indirect subsidiaries) to leave the employment of Vision 21;

                           ii)      act or serve, directly or indirectly, as a
principal, agent, independent contractor, consultant, director, officer,
employee, employer or advisor or in any other position or capacity with or for,
or acquire a direct or indirect ownership interest in or otherwise conduct
(whether as stockholder, partner, investor, joint venturer, or as owner of any
other type of interest), any Competing Management Business as such term is
defined herein; provided, however, that this clause (ii) shall not prohibit the
Physician from being the owner of up to 1% of any class of outstanding
securities of any company or entity if such class of securities is publicly
traded; or

                           iii)     directly or indirectly, either as principal,
agent, independent, contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's own benefit or
for the benefit of any other person or entity, call upon or solicit any
customers or clients of the



                                      -62-
<PAGE>   63

Management Business; provided however, that the Physician may send out a general
notice to the customers or clients of the Management Business announcing the
termination of his arrangement with Vision 21 and may advertise in a general
manner without violating this covenant. The parties hereto acknowledge and agree
that for purposes of this Section, patients which have in the past received
medical or optometric care from the Company or the Partnership and/or shall in
the future receive medical or optometric care from the New P.A. are not deemed
to be customers or clients of the Management Business.

                  b.       For the purposes of this Section 18.1, the
following terms shall have the meaning set forth below:

                           i)       "Management Business" shall mean management
and administration of the non-medical aspects of medical, ophthalmology and
optometry practices.

                           ii)      "Competing Management Business" shall mean
an individual, business, corporation, association, firm, undertaking, company,
partnership, joint venture, organization or other entity that either (A)
conducts a business substantially similar to the Management Business within the
State, or (B) provides or sells a service which is the same or substantially
similar to, or otherwise competitive with the services provided by the
Management Business within the State; provided, however, that "Competing
Management Business" shall not include Vision 21, or the Physician's internal
management and administration of the Physician's medical practice or
participation in the management and administration of a physician group in which
the Physician devotes a significant amount of time to the practice of medicine.

         c.       Should any portion of this Section 18.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Physician hereunder, and only in such event, then the
Physician and Vision 21 consent and agree to such limitation on scope, duration
or territory as may be finally adjudicated as enforceable by a court of
competent jurisdiction after the exhaustion of all appeals.

         d.       This covenant shall be construed as an agreement ancillary to
the other provisions of this Agreement, and the existence of any claim or cause
of action of the Physician against Vision 21, whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by
Vision 21 of this covenant; provided, however, that the Physician shall not be
bound by this covenant and shall not be obligated to pay the liquidated damages
contemplated in this Section 18.1 if at the time of a breach of this covenant
the Business Management Agreement has already been terminated pursuant to
Section 6.2(a) or 6.2(d) thereof. Without limiting other possible remedies to
Vision 21 for breach of this covenant, the Physician agrees that injunctive or
other equitable relief will be available to enforce the covenants of this
provision. The Physician and Vision 21 further expressly acknowledge that the
damages that would result from a violation of this non-competition covenant
would be impossible to predict with any degree of certainty, and agree that
liquidated damages in the amount of the aggregate consideration received by the
Physician 



                                      -63-
<PAGE>   64

pursuant to this Agreement is reasonable in light of the severe harm to the
Management Business and Vision 21 which would result in the event that a
violation of this non-competition covenant were to occur. For purposes of
calculation of the liquidated damages contemplated in this Section and for
purposes of calculation of the liquidated damages contemplated in the Business
Management Agreement and the Physician Employment Agreement between the
Physician and New P.A., the aggregate consideration received by Physician
pursuant to this Agreement shall be in those amounts and in such form as set
forth in Schedule 18.1. If the Physician violates this non-competition covenant,
Vision 21 shall, in addition to all other rights and remedies available at law
or equity, be entitled to (a) cancel the number of shares of Common Stock held
by the Physician or, with respect to shares of Common Stock entitled to be
received by the Physician, terminate its obligation to deliver such number of
shares of Common Stock valued as set forth in Section 6.6(a) of the Business
Management Agreement, and (b) repayment by Physician to Vision 21 of the fair
market value as described above of Vision 21 Common Stock sold by Physician; but
in no event shall Vision 21 be entitled to offset amounts in excess of the
liquidated damages sum pursuant to this Section 18.1. The Physician agrees to
deliver to Vision 21 the certificates representing any such shares canceled by
Vision 21. Payment and satisfaction by Physician shall be made within sixty (60)
days of notification to Physician by Vision 21 that Physician has violated this
non-competition covenant.

                  e.       Notwithstanding anything contained herein, this
Section 18.1 shall not be construed to (i) limit the freedom of any patient of
the Physician to choose the facility or physician from whom such patient shall
receive health-care services or (ii) limit or interfere with the Physician's
ability to exercise his professional medical judgment in treating his patients
or his ability to provide medical services to his patients.

         18.2.    Physician Confidentiality Covenant. From the date hereof, the
Physician shall not, directly or indirectly, use for any purpose, other than in
connection with the performance of the Physician's duties under the Physician
Employment Agreement with New P.A., or disclose to any third party, any material
information of Vision 21, the Company or the Partnership, as appropriate
(whether written or oral), including any business management or economic
studies, patient lists, proprietary forms, proprietary business or management
methods, marketing data, fee schedules, or trade secrets of Vision 21, of the
Company or of the Partnership, as applicable, and including the terms and
provisions of this Agreement and any transaction or document executed by the
parties pursuant to this Agreement. Notwithstanding the foregoing, the Physician
may disclose information that the Physician can establish (a) is or becomes
generally available to and known by the public or medical community (other than
as a result of an unpermitted disclosure directly or indirectly by the Physician
or his Affiliates, advisors, or representatives); (b) is or becomes available to
the Physician on a nonconfidential basis from a source other than Vision 21, the
Company, the Partnership or their respective Affiliates, advisors or
representatives, provided that such source is not and was not bound by a
confidentiality agreement with or other obligation of secrecy to Vision 21, the
Company, the Partnership or their respective Affiliates, advisors or
representatives of which the Physician has knowledge; or (c) has already been or
is hereafter independently acquired or developed by the Physician without



                                      -64-
<PAGE>   65

violating any confidentiality agreement with or other obligation of secrecy to
Vision 21, the Company, the Partnership or their respective Affiliates, advisors
or representatives. Without limiting the other possible remedies to Vision 21
for the breach of this covenant, the Physician agrees that injunctive or other
equitable relief shall be available to enforce this covenant. The Physician
further agrees that if any restriction contained in this Section 18.2 is held by
any court to be unenforceable or unreasonable, a lesser restriction shall be
enforced in its place and the remaining restrictions contained herein shall be
enforced independently of each other.

         18.3.    Survival. The parties acknowledge and agree that this Article
18 shall survive the Closing of the transactions contemplated herein.

         19.      DISPUTES.

         19.1.    Mediation and Arbitration. Any dispute, controversy or claim
(excluding claims arising out of an alleged breach of Article 18 of this
Agreement) arising out of this Agreement, or the breach thereof, that cannot be
settled through negotiation shall be settled (a) first, by the parties trying in
good faith to settle the dispute by mediation under the Commercial Mediation
Rules of the AAA (such mediation session to be held in Tampa, Florida and to
commence within 15 days of the appointment of the mediator by the AAA), and (b)
if the controversy, claim or dispute cannot be settled by mediation, then by
arbitration administered by the AAA under its Commercial Arbitration Rules (such
arbitration to be held in Tampa, Florida before a single arbitrator and to
commence within 15 days of the appointment of the arbitrator by the AAA), and
judgment on the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof.

         20.      MISCELLANEOUS

         20.1.    Taxes. Physician shall pay all transfer taxes, sales and other
taxes and charges imposed by the State, if any, which may become payable in
connection with the transactions and documents contemplated hereunder (excluding
any of such taxes which may be attributable to services to be provided by Vision
21 under the Business Management Agreement). Vision 21 shall pay all transfer
taxes, sales and other taxes and charges imposed by the State of Florida, if
any, which may become payable in connection with the transactions and documents
contemplated hereunder (excluding any of such taxes which may be attributable to
services to be provided by Vision 21 under the Business Management Agreement).

         20.2.    Remedies Not Exclusive. No remedy conferred by any of the
specific provisions of this Agreement or any document contemplated by this
Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise. The election of any one or more remedies by any party hereto shall
not constitute a waiver of the right to pursue other available remedies.

subject of this Agreement, and as to those matters the law of the state of
incorporation or organization of the respective entity shall govern.

         20.6.    Entire Agreement; Amendments and Waivers. This Agreement,
together with the documents contemplated by this Agreement and all Exhibits and
Schedules hereto and thereto, constitute the entire agreement between the
parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof. No
supplement, modification or waiver of any of the provisions of this Agreement
shall be binding unless it shall be specifically designated to be a supplement,
modification or waiver of this Agreement and shall be executed in writing by the
party to be bound thereby. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provision hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver
unless otherwise expressly provided.

         20.7.    Confidentiality Agreements. The provisions of any prior
confidentiality agreements and letters of intent between or among Vision 21, the
Company, the Partnership and the Physician, as amended, shall terminate and
cease to be of any force or effect at and upon the Closing.

         20.8.    Modification Clause. It is the intention of the parties hereto
to conform strictly to applicable laws regarding the practice and regulation of
medicine, whether such laws are now or hereafter in effect, including the laws
of the United States of America, the State or any other applicable jurisdiction,
and including any subsequent revisions to, or judicial interpretations of, those
laws, in each case to the extent they are applicable to this Agreement (the
"Applicable Laws"). Accordingly, if the ownership of any Nonmedical Asset by
Vision 21 violates any Applicable Law, then the parties hereto agree as follows:
(a) the provisions of this Section 20.8 shall govern and control; (b) if none of
the parties hereto are materially economically disadvantaged, then any
Nonmedical Asset, the ownership of which violates any Applicable Law, shall be
deemed to have never been owned by Vision 21; (c) if one or more of the parties
hereto is materially economically disadvantaged, then the parties hereto agree
to negotiate in good faith such changes to the structure and terms of the
transactions provided for in this Agreement as may be necessary to make these
transactions, as restructured, lawful under applicable laws and regulations,
without materially disadvantaging either party; (d) this Agreement shall be
deemed modified and amended; and (e) the



                                      -67-
<PAGE>   68

parties to this Agreement shall execute and deliver all documents or instruments
necessary to effect or evidence the provisions of this Section 20.8.

         20.9.    Assignment. The Agreement may not be assigned by operation of
law or otherwise except that Vision 21 shall have the right to assign this
Agreement, at any time, to any Affiliate or direct or indirect wholly-owned
subsidiary. In the event of such assignment, Vision 21 shall remain liable
hereunder.

         20.10.   Attorneys' Fees. Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to this
Agreement or the other documents contemplated with respect to the
interpretation, enforcement or breach hereof, the prevailing party in such
action shall be entitled to an award of all reasonable costs of litigation or
arbitration, including, without limitation, attorneys' fees, to be paid by the
losing party, in such amounts as may be determined by the court having
jurisdiction of such action or proceeding, by the arbitrators deciding such
action or proceeding or as agreed to be the parties hereto.

         20.11.   Further Assurances. From time to time hereafter and without
further consideration, each of the parties hereto shall execute and deliver such
additional or further instruments of conveyance, assignment and transfer and
take such other actions as any of the other parties hereto may reasonably
request in order to more effectively consummate the transactions contemplated
hereunder or as shall be reasonably necessary or appropriate in connection with
the carrying out of the parties' respective obligations hereunder for the
purposes of this Agreement.

         20.12.   Announcements and Press Releases. Any press releases or any
other public announcements concerning this Agreement or the transactions
contemplated hereunder shall be approved in advance by Vision 21; provided,
however, that if Physician or the Company reasonably believes that he or it has
a legal obligation to make a press release and the consent of Vision 21 cannot
be obtained, then the release may be made without such approval.

         20.13.   No Tax Representations. Each party acknowledges that it is
relying solely on its advisors to determine the tax consequences of the
transactions contemplated hereunder and that no representation or warranty has
been made by any party as to the tax consequences of such transactions except as
otherwise specifically set forth in this Agreement.

         20.14.   No Rights as Stockholder. The Physician shall have no rights
as a stockholder with respect to any shares of Common Stock until the issuance
of a stock certificate evidencing such shares. Except as otherwise provided in
the Agreement, no adjustment shall be made for dividends or distributions or
other rights for which the record date is prior to such date any stock
certificate is issued.



                                      -68-
<PAGE>   69

         20.15.   Multiple Counterparts. This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

         20.16.   Headings. The headings of the several articles and sections
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning or interpretation of this Agreement.

         20.17.   Severability. Each article, section and subsection of this
Agreement constitutes a separate and distinct undertaking, covenant or provision
of this Agreement. If any such provision shall finally be determined to be
unlawful, such provision shall be deemed severed from this Agreement, but every
other provision of this Agreement shall remain in full force and effect.

         20.18.   Form of Transaction. If after the execution hereof, Vision 21
determines that the ownership of the Nonmedical Assets of the Company and the
Partnership can be better achieved through a different form of transaction
without economic injury to the Company or the Physician, or delay of the
consummation of the transaction, the Company and the Physician shall cooperate
(and the Company shall use its best efforts to cause the Partnership to
cooperate) in revising the structure of the transaction and shall negotiate in
good faith to so amend this Agreement; provided, that Vision 21 shall reimburse
the Company, the Partnership and the Physician at Closing for all reasonable
additional expenses incurred by the Company, the Partnership and the Physician
as a result of such change in form.

                          ASSET PURCHASE AGREEMENT

         This Asset Purchase Agreement (this "Agreement"), effective as of
September 1, 1997, is by and among THOMAS J. PUSATERI, M.D., P.A., a Florida
professional association (the "Company"), THOMAS J. PUSATERI, M.D. (the
"Physician"), and VISION TWENTY-ONE, INC., a Florida corporation ("Vision 21").

                               R E C I T A L S

         A.      Physician is a physician licensed to practice medicine in the
State (as defined herein) and currently employs ophthalmologists and conducts
an ophthalmology practice through the Company and through optometrist employees
currently conducts an optometry practice through the Company.

            
         B.      Physician owns all of the issued and outstanding shares of
capital stock of the Company.

         C.      Vision 21 provides business management services and facilities
for eye care professionals and related businesses.

         D.      The Company is a partner with Florida Eye Center, Sever &
Ramseur, M.D., P.A., a Florida professional association ("Sever & Ramseur,
P.A."), and Leonard E. Cortelli, M.D., P.A., a Florida professional association
("Cortelli, P.A."), in a Florida partnership known as Florida Eye Center (the
"Partnership").

         E.      Simultaneously herewith, the Partnership shall distribute all
of its assets and assign all of its liabilities to Cortelli, P.A., the Company
and Sever & Ramseur, P.A.

         F.      Following such transfers and assignments by the Partnership,
Vision 21 intends to purchase, assume and acquire all of the Company's, Sever &
Ramseur, P.A.'s and Cortelli, P.A.'s respective assets to the extent provided
by law and to assume certain liabilities of the Company, Sever & Ramseur, P.A.
and Cortelli, P.A., in exchange for capital stock of Vision 21 and other
consideration, all as more specifically provided herein.

         G.      The Company desires to sell, assign and transfer all of its
assets to the extent permitted by law to Vision 21 and to have Vision 21 assume
certain of the Company's liabilities, all in accordance with the terms and
conditions of this Agreement.

         H.      Vision 21 cannot acquire certain of the Company's, Sever &
Ramseur, P.A.'s or Cortelli, P.A.'s respective assets because of laws
prohibiting general business corporations from engaging in the practice of
medicine or optometry, exercising control over physicians practicing medicine
or optometrists practicing optometry, or engaging in certain practices such as
fee splitting with physicians or optometrists.





<PAGE>   2



         I.      In order to effect such acquisition, the Company, Sever &
Ramseur, P.A. and Cortelli, P.A. intend to form a new professional association
("New P.A.") and to transfer their respective medical businesses and all of
their Medical Assets (as defined herein) to New P.A. in exchange for shares of
New P.A.'s capital stock.

         J.      Simultaneously herewith, Sever & Ramseur, P.A. and Cortelli,
P.A. shall each enter into an acquisition agreement with Vision 21.

and enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies.  Except as set forth in Schedule 3.13, no

the Company, the Partnership or the Physician has received any notice or other
communication from any issuer of any Insurance Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, and to
the actual knowledge of the Company, no such cancellation or increase of
deductibles, retainages or premiums is threatened.  Except as set forth on
Schedule 3.13, none of the Company, the Partnership, the Physician or any
Professional Employee has any outstanding claims, settlements or premiums owed
against any Insurance Policy, and the Company, the Partnership, the Physician
and each Professional Employee have given all notices or has presented all
potential or actual claims under any Insurance Policy in due and timely
fashion.  Except as set forth on Schedule 3.13, since January 1, 1994, none of
the Company, the Partnership, the Physician or any Professional Employee has
filed a written application for any professional liability insurance coverage
which has been denied by an insurance agency or carrier, and the Company, the

3.14 is a true and correct description of the following ("Proprietary Rights"):

trade designations, including common law rights, registrations and applications
therefor, and all patents and applications therefor currently owned, in whole
or in part, by the Company or the Partnership and all licenses, royalties,
assignments and other similar agreements relating to the foregoing to which
either the Company or the Partnership is a party (including the expiration date
thereof if applicable); and

                 b.       all agreements relating to technology, know-how or
processes that the Company or the Partnership has licensed or authorized to use
by others (other than technology, know-how or processes generally available to
other health care providers), or which either the Company or the Partnership
licenses or authorizes others to use.

The Company and/or the Partnership own or have the legal right to use the
Proprietary Rights, and to the knowledge of the Company, such ownership or use
does not  conflict, infringe or violate the rights of any other person.  Except
as disclosed on Schedule 3.14, no consent of any person will be required for
the use thereof by Vision 21 upon consummation of the transactions contemplated
hereby and the Proprietary Rights are freely transferable.  No claim has been
asserted by any person to the ownership of or for infringement by the Company
or the Partnership of the proprietary right of any other person, and the
Company does not know of any valid basis for any such claim.  To the best
knowledge of the Company and the Physician, the Company and the Partnership
have the right to use, free and clear of any adverse claims or rights of
others, all trade secrets, customer lists and

excise, corporate, franchise, property, sales, use, payroll, withholding,
provider, value added and other tax returns and reports (collectively the "Tax

political subdivision thereof or any foreign jurisdiction.  All such Tax
Returns or reports are complete and accurate in all material respects and
properly reflect the taxes of the Company and the Partnership for the periods
covered thereby.

                 b.       Payment of Taxes.  Except for such items as the
Company or the Partnership may be disputing in good faith by proceedings in
compliance with applicable law, which are described on Schedule 3.15, (i) the

interest that have become due with respect to any Tax Returns they have filed
and have properly accrued on their respective books and records for all of the
same that have not yet become due, and (ii) neither the Company nor the
Partnership is delinquent in the payment of any tax, assessment or governmental
charge.

                 c.       No Pending Deficiencies, Delinquencies, Assessments
or Audits.  Except as set forth on Schedule 3.15, neither the Company nor the
Partnership has received any notice that any tax deficiency or delinquency has
been asserted against the Company or the Partnership.  There is no unpaid
assessment, proposal for additional taxes, deficiency or delinquency in the
payment of any of the taxes of the Company or the Partnership that could be

best of the Company's knowledge, violated any federal, state, local or foreign
tax law.

Company nor the Partnership has granted an extension to any taxing authority of
the limitation period during which any tax liability may be assessed or
collected.

required to be withheld by the Company or the Partnership and paid to
governmental agencies for all income, social security, unemployment insurance,
sales, excise, use, and other taxes have been collected or withheld and paid to
the respective governmental agencies.

                 f.       Foreign Person.  None of the Company, the Partnership

         3.16.   Compliance with Laws.  Neither the Company nor the Partnership
has failed, and neither the Company nor the Physician is aware of any failure
by the Physician or any Professional Employee to comply with all applicable
laws, regulations and licensing requirements relating to the operation of the

respective businesses as now conducted, all of which are listed (with

transactions contemplated hereby.  None of the Company, the Partnership or the
Physician is (a) subject to any continuing court or administrative order,
judgment, writ, injunction or decree applicable specifically to the Nonmedical
Assets, the Company, the Partnership or to their businesses, assets, operations

law, including, without limitation, the registration requirements of applicable
federal and state securities laws.

         5.9.    Vision 21 Financial Statements.  The audited consolidated

joint venture, trust or other entity, and Vision 21 does not know of any valid
basis for the assertion of any other claims or liabilities of any nature or in
any amount.

         5.11.   Compliance with Laws.  Vision 21 has not failed to comply with
any applicable laws, regulations and licensing requirements or failed to file
with the proper authorities any necessary statements and reports except where
the failure to so comply or file would not, individually or in the aggregate,
have a material adverse effect on the Transaction.  There are no existing
violations by Vision 21 of any federal, state or local law or regulation that
could, individually or in the aggregate, have a material adverse effect on the
Transaction.  Vision 21 possesses all necessary licenses, franchises, permits
and governmental authorizations for the conduct of Vision 21's business as now
conducted and after the Closing, as contemplated in this Agreement and the
Business Management Agreement, except for such licenses, franchises, permits or
governmental authorizations which, if not possessed by Vision 21, would not
have a material adverse effect on the business of Vision 21.  The transactions
contemplated by this Agreement will not result in a default under or a breach
or violation of, or adversely affect the rights and benefits afforded by any
such licenses, franchises, permits or government authorizations, except for any
such default, breach or violation that would not, individually or in the
aggregate, have a material adverse effect on the Transaction or the performance
of the services contemplated under the Business Management Agreement.  Since
January 1, 1993, Vision 21 has not received any notice from any federal, state
or other governmental authority or agency having jurisdiction over its
properties or activities, or any insurance or inspection body, that its
operations or any of its properties, facilities, equipment, or business
practices fail to comply with any applicable law, ordinance, regulation,
building or zoning law, or requirement of any public or quasi-public authority
or body, except where failure to so comply would not, individually or in the
aggregate, have a material adverse effect on the Transaction.

         5.12.   Insolvency Proceedings.  Vision 21 is not currently under the
jurisdiction of a  Federal or state court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

         5.13.   Employment of Company's Employees.  Vision 21 does not
currently intend to change the existing composition or employment terms of any
of the non-professional personnel which have employment arrangements with the
Company or the Partnership on the effective date of this Agreement (except as
is necessary for Vision 21 to employ such individuals pursuant to the Business
Management Agreement).  Vision 21 reserves the right, however, to change the
number, composition or employment terms of such non-professional personnel in
the future.

<PAGE>   36



                 a.       Physician understands that the Securities will not be
registered under the Securities Act or any state securities laws on the grounds
that the issuance of the Securities is exempt from registration pursuant to
Section 4(2) of the Securities Act under the Securities Act and applicable
state securities laws, and that the reliance of Vision 21 on such exemptions is
predicated in part on the Physician's representations, warranties, covenants
and acknowledgements set forth in this Section.

                 b.       Except as disclosed on Schedule 6.1(b) attached
hereto, Physician represents and warrants that Physician is an "accredited
investor" or "sophisticated investor" as defined under the Securities Act and
state "Blue Sky" laws, or that Physician has utilized, to the extent necessary
to be deemed a sophisticated investor under the Securities Act and State "Blue
Sky" laws, the assistance of a professional advisor.

                 c.       Physician represents and warrants that the Securities
to be acquired by Physician upon consummation of the transactions described in
this Agreement will be acquired by Physician for Physician's own account, not
as a nominee or agent, and without a view to resale or other distribution
within the meaning of the Securities Act and the rules and regulations
thereunder, except as contemplated in this Agreement, and that Physician will
not distribute any of the Securities in violation of the Securities Act.  All
Securities shall bear a restrictive legend in substantially the following form:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE
         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

         In addition, the Securities shall bear any legend required by the
securities or "Blue Sky" laws of any state where Physician resides as well as
any other legend deemed appropriate by Vision 21 or its counsel.

                 d.       Physician represents and warrants that the address
set forth below Physician's name on Schedule 6.1(d) is Physician's principal
residence.

                 e.       Physician (i) acknowledges that the Securities issued
to Physician at the Closing must be held indefinitely by Physician unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that
in such cases where the Rule is not applicable, compliance with some other
registration exemption will be required, and (iii) is aware that Rule 144 is
not currently available for use by Physician for resale of any of the
Securities to be acquired by Physician upon consummation of the transactions
described in this Agreement.

<PAGE>   37



                 f.       Physician represents and warrants to Vision 21 that
Physician, either alone or together with the assistance of Physician's own
professional advisor, has such knowledge and experience in financial and
business matters such that Physician is capable of evaluating the merits and
risks of Physician's investment in any of the Securities to be acquired by
Physician upon consummation of the transactions described in this Agreement.

                 g.       Physician confirms that Physician has had the
opportunity to ask questions of and receive answers from Vision 21 concerning
the terms and conditions of Physician's investment in the Securities, and the
Physician has received to Physician's satisfaction, such additional
information, in addition to that set forth herein, about Vision 21's operations
and the terms and conditions of the offering as Physician has requested.

                 h.       In order to ensure compliance with the provisions of
paragraph (c) hereof, Physician agrees that after the Closing Physician will
not sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the Securities Act) without
first complying with either of the following conditions, the expenses and costs
of satisfaction of which shall be fully borne and paid for by Physician:

                          i)      Vision 21 shall have received a written legal
opinion from legal counsel, which opinion and counsel shall be satisfactory to
Vision 21 in the exercise of its reasonable judgment, or a copy of a "no-
action" or interpretive letter of the Securities and Exchange Commission
specifying the nature and circumstances of the proposed transfer and indicating
that the proposed transfer will not be in violation of any of the registration
provisions of the Securities Act and the rules and regulations promulgated
thereunder; or

                          ii)     Vision 21 shall have received an opinion from
its own counsel to the effect that the proposed transfer will not be in
violation of any of the registration provisions of the Securities Act and the
rules and regulations promulgated thereunder.

Physician also agrees that the certificates or instruments representing the
Securities to be issued to Physician pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this
Section and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 6.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.

                 i.       Physician understands that there can be no assurance
that a Public Offering by Vision 21 will ever occur or if it does occur that it
will be successful.





                                    -37-

                 j.       Physician agrees that he shall be considered an
"affiliate" of Vision 21 for purposes of Rule 144 and agrees to the
restrictions and limitations imposed by Rule 144 on affiliates.  Physician
further agrees that he shall be considered an affiliate of Vision 21 for Rule
144 purposes even if he does not meet the technical definition of "affiliate"
under Rule 144.

         6.2.    Current Public Information.  At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act,
as such Rule may be amended from time to time (or any similar rule or
regulation hereafter adopted by the SEC) regarding the availability of current
public information to the extent required to enable any holder of shares of
Common Stock to sell such shares without registration under the Securities Act
pursuant to Rule 144 (or any similar rule or regulation).

Partnership and Physician agrees at or immediately prior to Closing (i) to
terminate his employment agreement, if any, with the Company or the Partnership
by mutual consent without any liability therefor on the part of the Company or
the Partnership, and (ii) to enter into a new Physician Employment Agreement

Agreement.

         8.17.   Optometrist Employment Agreements.  The Company, the

         8.18.   Termination of Retirement Plans.  Prior to Closing, the

to take all steps necessary to discontinue benefits accruals under any Employee
Benefit Plan that is intended to be a qualified employee retirement plan under
Section 401(a) of the Code (a "Retirement Plan") effective as of Closing or as
soon thereafter as may be practical.  Effective at the time of Closing, the
Company and the Partnership shall cause New P.A. to assume all of the
obligations of the Company and the





                                    -43-
<PAGE>   44

Partnership as the sponsoring employer and/or plan administrator of the
Retirement Plan in compliance with applicable law.

                 Subsequent to Closing, the New P.A. and Vision 21 shall review
the extent to which the New P.A. can resume contributions to the Retirement
Plan without violating the qualification requirements of Sections 410(b) and
401(a)(4) of the Code, taking into account any employees of Vision 21 who would
be "leased employees" of the New P.A.  under Section 414(n) of the Code.  If
Vision 21 and the New P.A. mutually agree that such qualification requirements
can be satisfied, the Company may elect to continue the Retirement Plan and
make contributions in accordance with its terms, provided that the New P.A.
shall agree to cover at its own expense any Vision 21 employees who are leased
employees if such coverage is required to maintain the tax-qualified status of
the Retirement Plan.

         8.19.   Delivery of Schedules.  The Company and the Physician shall
deliver to Vision 21 all Schedules required to be delivered by them prior to
the Closing.

         8.20.   Assignment of Fees for Medical and Optometry Services.  On or
prior to the Closing Date, the Company shall obtain an irrevocable assignment
from all Professional Employees of any and all of their rights to receive
payment for the provision of ophthalmology or optometry services which are part
of the Accounts Receivable to Vision 21 existing on the Closing Date, except
for those fees specified and set forth on Schedule 8.20.  Each Professional
Employee shall undertake to endorse any payments received on account of such
services to the order of Vision 21 and to take such other action as may be
necessary to confirm to Vision 21 the rights to collect and retain for its own
account such Accounts Receivable.  The Company shall cause its Professional
Employees to agree that such security interest of such lender(s) is intended to
be a first priority security interest and is superior to any right, title or
interest which may be asserted by such Professional Employees with respect to
the Accounts Receivable or the proceeds thereof.  In the event that the
assignment of rights described in this Section shall be deemed, for any reason,
to be ineffective as an outright assignment, the Company shall cause each
Professional Employee to agree that such Professional Employee shall be deemed,
effective as of the Closing Date, to have granted to Vision 21 a first priority
lien on and security interest in and to any and all interests of such
Professional Employee in any of the Accounts Receivable, and all proceeds with
respect thereto, to secure the collection by Vision 21 of all Accounts
Receivable, and this Agreement shall be deemed to be a security agreement to
the extent necessary to give effect to the foregoing.  The Company shall cause
each Professional Employee to execute and deliver, all such financing
statements as the Company or Vision 21 may request in order to perfect such
security interest.  The Company shall not suffer any Professional Employee to
grant any other lien on or security interest in or to such Accounts Receivable
or any proceeds thereof.

         9.      COVENANTS OF VISION 21.  Vision 21 agrees that between the
date hereof and the Closing:

time or both, would become a default, received by Vision 21 subsequent to the
date of this Agreement and prior to the Closing Date under any agreement or
commitment entered into by Vision 21 material to Vision 21's condition
(financial or otherwise), operations, assets, liabilities or business and to
which it is subject; or (b) any material adverse change in Vision 21's
condition (financial or otherwise), operations, assets, liabilities or
business.

         9.3.    Licenses and Permits.  Vision 21 shall use its best efforts to

desirable to consummate the Transaction or provide the services contemplated by
the Business Management Agreement and to conduct the intended business of
Vision 21.

identified on Schedule 9.4 and assumed by Vision 21 pursuant to the terms of
this Agreement.

         9.5.    Approvals of Third Parties.  Vision 21 shall use its best

accordance with this Section 10.1 and Vision 21 does not consent to such

(the "Escrow Agent") shall release the agreements, certificates, instruments,
documents and other materials described in Sections 13.1 and 13.2 to the

Agreement only after all such materials have been delivered by all applicable

establish a local advisory council composed of delegates from certain practice
groups acquired by Vision 21 in connection with the Recent Acquisitions,
delegates from the New P.A. and delegates from Vision 21.  Such delegates shall
be appointed from practice groups which are located in a market area to be
identified by Vision 21 and in which the New P.A. is located.  The local

the market area as to policy and strategy issues and shall determine certain
types of issues and disputes between Vision 21 and such





                                    -52-
<PAGE>   53

practice groups which issues and disputes are identified in the Business
Management Agreement and other management agreements entered into between
Vision 21 and practice groups.  New P.A. shall have the right to appoint one
(1) member to a local advisory council who shall serve an initial two (2) year
term.  After the initial two-year term, election of members to the local
advisory council shall be in accordance with by-laws which shall be adopted and

approve as limited herein certain decisions of the local advisory councils, and
to resolve deadlocks among the members of such local advisory councils.

         14.3.   Access to Books and Records.  From and after the Closing Date,
at the request of any party hereto, each of the other parties shall reasonably
cooperate in providing the requesting party with access to such other parties'
personnel who are knowledgeable concerning, and books and records which are
relevant to, the inquiry by the requesting party; provided, however, that (a)
such personnel shall be available at, and the access to such books and records
shall be granted at the responding party's business premises and during the
responding party's regular business hours, and (b) the inquiry shall be for a
legitimate business purpose, including tax filings and compliance, defending
against litigation or other claims, or for any other legitimate business
purpose.  All copies of such books and records shall be at the requesting
party's expense.  Each of the parties to this Agreement shall retain all books
and records with respect to the transactions contemplated herein for a minimum
of five (5) years from the Closing Date.

         15.     REMEDIES.

         15.1.   Indemnification by the Company and Physician.  Subject to the
terms and conditions of this Agreement, the Company and the Physician, jointly
and severally, agree to indemnify, defend and hold Vision 21 and its directors,
officers, employees, agents, attorneys and affiliates harmless from and against
all losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (collectively,
"Damages") asserted against or incurred by such entities and individuals
(including, but not limited to, any reduction in payments to or revenues of the
New P.A.) arising out of or resulting from:

                 a.       a breach of any representation, warranty or covenant
of the Company or the Physician contained herein or in any schedule or
certificate delivered hereunder;

                 b.       any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation,
at common law or otherwise, (i) arising out of or based upon any untrue
statement or alleged untrue statement of a material fact relating to the
Physician or the Company (including its subsidiaries, if any), the Partnership
or New P.A., and provided to Vision 21 or its counsel by the Company or the
Physician, specifically for inclusion in a Registration Statement or any
prospectus forming a part thereof, or any amendment thereof or supplement
thereto, (ii) arising out of or based upon any omission or alleged omission to
state therein a material fact relating to the Physician or the Company
(including its subsidiaries, if any),





                                    -53-
<PAGE>   54

the Partnership or New P.A. required to be stated therein or necessary to make
the statements therein not misleading, and not provided to Vision 21 or its
counsel by the Company or the Physician, provided, however, that such indemnity
shall not inure to the benefit of Vision 21 to the extent that such untrue
statement (or alleged untrue statement) was made in, or omission (or alleged
omission) occurred in, any preliminary prospectus, and such information was not
so included by Vision 21 and properly delivered to shareholders of Vision 21
who acquire Vision 21 Common Stock in any Public Offering;

                 c.       any filings, reports or disclosures made pursuant to
the IRS Voluntary Compliance Resolution Program, if applicable; and

                 d.       any liability arising from any alleged unlawful sale
or offer to sell or transfer any of the Common Stock by Physician.

         15.2.   Indemnification by Vision 21.  Subject to the terms and
conditions of this Agreement, Vision 21 hereby agrees to indemnify, defend and
hold the Company and the Physician harmless from and against all damages
asserted against or incurred by it or him arising out of or resulting from:

                 a.       a breach by Vision 21 of any representation, warranty
or covenant of Vision 21 contained therein or in any schedule or certificate
delivered hereunder;

                 b.       any liability under the Securities Act, the Exchange
Act or any other federal or state "Blue Sky" or securities law or regulation,
at common law or otherwise, arising out of or based upon any untrue statement
or alleged untrue statement of a material fact relating to Vision 21, contained
in any preliminary prospectus, Registration Statement or any prospectus forming
a part thereof, or any amendment thereof or supplement thereto, arising out of
or based upon any omission or alleged omission to state therein a material fact
relating to Vision 21 (including its subsidiaries), required to be stated
therein or necessary to make the statements therein not misleading; and

                 c.       any filings, reports or disclosures made pursuant to
the IRS Voluntary Compliance Resolution Program, if applicable.

         Notwithstanding anything in this Section 15.2, Vision 21 shall not be
liable for any Damages resulting from any matter not disclosed to Vision 21 by
any of the third parties acquired by Vision 21 in connection with the Recent
Acquisitions.

         15.3.   Conditions of Indemnification.  All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                 a.       A party claiming indemnification under this Agreement
(an "Indemnified Party") shall promptly (and, in any event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party from whom indemnification





                                    -54-
<PAGE>   55

is sought (the "Indemnifying Party") of any third-party claim or claims
asserted against the Indemnified Party ("Third Party Claim") that could give
rise to a right of indemnification under this Agreement and (ii) transmit to
the Indemnifying Party a written notice ("Claim Notice") describing in
reasonable detail the nature of the Third Party Claim, a copy of all papers
served with respect to such claim (if any), an estimate of the amount of
damages attributable to the Third Party Claim and the basis of the Indemnified
Party's request for indemnification under this Agreement.  Except as set forth
in Section 15.6, the failure to promptly deliver a Claim Notice shall not
relieve the Indemnifying Party of its obligations to the Indemnified Party with
respect to the related Third Party Claim except to the extent that the
resulting delay is materially prejudicial to the defense of such claim.  Within
thirty (30) days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Party shall notify the Indemnified Party (i) whether the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 15 with respect to such Third Party Claim and (ii) whether
the Indemnifying Party desires, at the sole cost and expense of the
Indemnifying Party, to defend the Indemnified Party against such Third Party
Claim.

                 b.       If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have
the right to defend, at its sole cost and expense, such Third Party Claim by
all appropriate proceedings, which proceedings shall be prosecuted diligently
by the Indemnifying Party to a final conclusion or settled at the discretion of
the Indemnifying Party in accordance with this Section 15.3(b).  The
Indemnifying Party shall have full control of such defense and proceedings,
including any compromise or settlement thereof.  The Indemnified Party is
hereby authorized, at the sole cost and expense of the Indemnifying Party (but
only if the Indemnified Party is entitled to indemnification hereunder), to
file, during the Election Period, any motion, answer or other pleadings that
the Indemnified Party shall deem necessary or appropriate to protect its
interests or those of the Indemnifying Party and not prejudicial to the
Indemnifying Party (it being understood and agreed that if an Indemnified Party
takes any such action that is prejudicial and causes a final adjudication that
is adverse to the Indemnifying Party, the Indemnifying Party shall be relieved
of its obligations hereunder with respect to such Third Party Claim).  If
requested by the Indemnifying Party, the Indemnified Party agrees, at the sole
cost and expense of the Indemnifying Party, to cooperate with the Indemnifying
Party and its counsel in contesting any Third Party Claim that the Indemnifying
Party elects to contest, including, without limitation, the making of any
related counterclaim against the person asserting the Third Party Claim or any
cross-complaint against any person.  The Indemnified Party may participate in,
but not control, any defense or settlement of any Third Party Claim controlled
by the Indemnifying Party pursuant to Section 15.3(b) and shall bear its own
costs and expenses with respect to such participation; provided, however, that
if the named parties to any such action (including any impleaded parties)
include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action
or separate but substantially 





                                    -55-
<PAGE>   56

similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys at any time for the
Indemnified Party, which firm shall be designated in writing by the Indemnified
Party.

                 c.       If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 15.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
15.3(b) but fails diligently and promptly to prosecute or settle the Third
Party Claim, then the Indemnified Party shall have the right to defend, at the
sole cost and expense of the Indemnifying Party (if the Indemnified Party is
entitled to indemnification hereunder), the Third Party Claim by all
appropriate proceedings, which proceedings shall be promptly and vigorously
prosecuted by the Indemnified Party to a final conclusion or settled.  The
Indemnified Party shall have full control of such defense and proceedings,
provided, however, that the Indemnified Party may not enter into, without the
Indemnifying Party's consent, which shall not be unreasonably withheld, any
compromise or settlement of such Third Party Claim.  Notwithstanding the
foregoing, if the Indemnifying Party has delivered a written notice to the
Indemnified Party to the effect that the Indemnifying Party disputes its
potential liability to the Indemnified Party under this Article 15 and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnifying
Party's defense pursuant to this Section or of the Indemnifying Party's
participation therein at the Indemnified Party's request, and the Indemnified
Party shall reimburse the Indemnifying Party in full for all costs and expenses
of such litigation.  The Indemnifying Party may participate in, but not control
any defense or settlement controlled by the Indemnified Party pursuant to this
Section 15.3(c), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party
has been advised by counsel that there may be one or more legal defenses
available to the Indemnified Party, then the Indemnifying Party may employ
separate counsel and upon written notification thereof, the Indemnified Party
shall not have the right to assume the defense of such action on behalf of the
Indemnifying Party.

                 d.       In the event any Indemnified Party should have a
claim against any Indemnifying  Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall  transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.  If the Indemnifying Party does not notify the
Indemnified Party within sixty (60) days from its receipt of the Indemnity
Notice that the Indemnifying Party disputes such claim, the claim specified by
the Indemnified Party in the Indemnity Notice shall be deemed a liability of
the Indemnifying Party hereunder.  If the Indemnifying Party has timely
disputed such claim, as provided above, such dispute shall be resolved by
mediation or arbitration as provided in Section 19.1 if the parties do not
reach a settlement of such dispute within thirty (30) days after notice of a
dispute is given.





                                    -56-
<PAGE>   57



                 e.       Payments of all amounts owing by an Indemnifying
Party pursuant to this Article 15 relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim or (iii) the expiration of the period
for appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.  Payments of all amounts owing by an
Indemnifying Party pursuant to Section 15.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the sixty (60) day Indemnity
Notice period or (ii) the expiration of the period for appeal, if any, of a
final adjudication or arbitration of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

         15.4.   Remedies Not Exclusive.  The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity.  This Article 15
regarding indemnification shall survive Closing.

         15.5.   Costs, Expenses and Legal Fees.  Each party hereto agrees to
pay the costs and expenses (including attorneys' fees and expenses) incurred by
the other parties in successfully (a) enforcing any of the terms of this
Agreement, or (b) proving that another party breached any of the terms of this
Agreement.

         15.6.   Indemnification Limitations.  Notwithstanding the provisions
of Sections 15.1 and 15.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2., 3.3, 3.11,
3.14, 4.3, 4.5, 4.7, 5.1, 5.2, 5.3, 5.4 and 6.1 may be made at any time, and a
claim for indemnification for a breach of the representations and warranties
contained in Sections 3.9, 3.15, 3.17, 3.18, 3.24, 3.25, 3.26, 3.27, 3.28,
3.30, 4.1, 4.4, 4.6, 5.6 and 5.7 may be made at any time within the applicable
statute of limitations; (b) indemnification based upon Sections 15.1(b) through
(d) and 15.2(b) may be made at any time within the applicable statute of
limitations; and (c) the Physician shall not be required to indemnify Vision 21
pursuant to Section 15.1 unless, and to the extent that, the aggregate amount
of Damages incurred by Vision 21 shall exceed an amount equal to two percent
(2%) of the total Purchase Price; and (c) the Physician shall not be required
to indemnify Vision 21 with respect to a breach of a representation, warranty
or covenant for Damages in excess of the aggregate Purchase Price received by
the Physician (other than pursuant to a requirement to indemnify Vision 21
under Sections 3.27 or 3.28, or unless the breach involves an intentional
breach or fraud by the Physician which shall be unlimited).

         15.7.   Tax Benefits; Insurance Proceeds.  The total amount of any
indemnity payments owed by one party to another party to this Agreement shall
be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds and such
correlative insurance benefit shall be net of the insurance premium, if any,
that becomes due as a result of such claim.

         15.8.   Payment of Indemnification Obligation.  In the event that the
Physician has an indemnification obligation to Vision 21 hereunder, subject to
Vision 21's approval as set forth below, the Physician may satisfy such
obligation by transferring to Vision 21 such number of shares of Vision 21
Common Stock owned by the Physician having an aggregate fair market value
(which is the fair market value at such time based on the last reported sale
price of Vision 21 Common Stock on a principal national securities exchange or
other exchange on which the Vision 21 Common Stock is then listed or the last
quoted ask price on any over-the-counter market through which the Vision 21
Common Stock is then quoted on the last trading day immediately preceding the
day on which the Physician transfers shares of Vision 21 Common Stock to Vision
21 hereunder) equal to the indemnification obligation, provided that each of
the following conditions are satisfied:

                 a.       The Physician shall transfer to Vision 21 good, valid
and marketable title to the shares of Vision 21 Common Stock, free and clear of
all adverse claims, security interests, liens, claims, proxies, options,
stockholders' agreements and encumbrances;

                 b.       The Physician shall make such representation and
warranties as to title to the stock, absences of security interests, liens,
claims, proxies, stockholders' agreements and other encumbrances and other
matters as reasonably requested by Vision 21; and

                 c.       The other terms and conditions of any transaction
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21.

         16.     TERMINATION.

         16.1.   Termination.  This Agreement may be terminated and the
Transaction may be abandoned:

                 a.       at any time prior to the Closing Date by mutual
agreement of all parties;

                 b.       at any time prior to the Closing Date by Vision 21 if
any representation or warranty of the Company or the Physician contained in
this Agreement or in any certificate or other document executed and delivered
by the Company or the Physician pursuant to this Agreement is or becomes untrue
or breached in any material respect or if the Company or the Physician fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt of written notice thereof;

                 c.       at any time prior to the Closing Date by the Company
if any representation or warranty of Vision 21 contained in this Agreement is
or becomes untrue in any material respect or if Vision 21 fails to comply in
any material respect with any covenant or agreement contained herein, and any
such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt or written notice thereof;





                                    -58-
<PAGE>   59



                 d.       at any time prior to the Closing Date by the Company
in the event of the failure of any of the conditions precedent set forth in
Article 12 of this Agreement;

                 e.       at any time prior to the Closing Date by Vision 21 in
the event of the failure of any of the conditions precedent set forth in
Article 11 of this Agreement;

                 f.       by Vision 21 if at any time prior to the Closing
Date, Vision 21 deems termination to be advisable, provided, however, that if
Vision 21 exercises its right to terminate this Agreement under this
subsection, Vision 21 shall reimburse the Company and the Physician for all
reasonable attorneys' and accountants' fees incurred by the Company and the
Physician in connection with this Agreement; provided that Vision 21 shall only
reimburse the Company and the Physician up to an aggregate maximum amount of
One Hundred Thousand and No/100 Dollars ($100,000.00) for such fees; or

                 g.       by Vision 21 or the Company if the Transaction shall
not have been consummated by November 30, 1997.

         16.2.   Effect of Termination.  In the event this Agreement is
terminated pursuant to Section 16.1, Vision 21, the Company and the Physician,
shall each be entitled to pursue, exercise and enforce any and all remedies,
rights, powers and privileges available at law or in equity, subject to the
limitations set forth in Section 15.1.  In the event of a termination of this
Agreement under the provisions of this Article 16, a party not then in material
breach of this Agreement shall stand fully released and discharged of any and
all obligations under this Agreement.

         17.     PHYSICIAN EMPLOYMENT AGREEMENT.

         17.1.   Physician Employment Agreement.  The parties acknowledge that
in accordance with the terms of this Agreement, Physician, as employee, and the
New P.A., as employer, have entered into the Physician Employment Agreement and
that Vision 21 is entitled to enforce such Physician Employment Agreement as an
intended third party beneficiary.  Physician and Vision 21 acknowledge that
Vision 21 would suffer severe harm in the event of Physician's resignation
prior to the expiration of the five (5) year term of such Physician Employment
Agreement (without first obtaining the written consent of Vision 21) or a
breach or default of Physician's obligations under such Physician Employment
Agreement, and Physician, the Company and Vision 21 agree that Vision 21 shall
be entitled to recover from Physician any and all damages incurred by Vision 21
caused by such resignation, breach or default.  Notwithstanding the foregoing,
Vision 21 shall not be entitled to recover its damages caused by such
resignation, breach or default if such resignation, breach or default was
caused by:  (i) the death or disability of Physician, (ii) circumstances not
caused by an act or omission of Physician and which circumstances are beyond
his control, or (iii) loss of Physician's license to practice as an
ophthalmologist, unless such loss of license is due to an act or omission of
Physician.  Notwithstanding the foregoing, Physician shall have no obligation
to pay the damages contemplated in this Section 17.1 if (a) the Business
Management Agreement has been terminated pursuant to a material breach by
Vision 21, or (b) Physician cures any such breach





                                    -59-
<PAGE>   60

or default of the Physician Employment Agreement within a period of thirty (30)
days after notice from Vision 21 of such breach or default.

         17.2.   Survival.  The parties acknowledge and agree that this Article
17 shall survive the Closing of the transactions contemplated herein.

         18.     NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

         18.1.   Physician and Company Non-Competition Covenant.

                 a.       The Physician and the Company recognize that the
covenants of the Physician and the Company contained in this Section 18.1 are
an essential part of this Agreement and that, but for the agreement of the
Physician and the Company to comply with such covenants, Vision 21 would not
have entered into this Agreement.  The Physician and the Company acknowledge
and agree that the Physician's and the Company's covenants not to compete are
necessary to ensure the continuation of the Management Business (as defined
below) and are necessary to protect the reputation of Vision 21, and that
irreparable and irrevocable harm and damage will be done to Vision 21 if the
Physician or the Company compete with the Management Business or Vision 21.
The Physician and the Company accordingly agree that for the periods set forth
in the Business Management Agreement the Physician and the Company shall not:

                          i)      directly or indirectly, either as principal,
agent, independent contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's or the Company's
own benefit or for the benefit of any other person or entity knowingly (A)
hire, attempt to hire, contact or solicit with respect to hiring any employee
of Vision 21 (or of any of its direct or indirect subsidiaries) or (B) induce
or otherwise counsel, advise or encourage any employee of Vision 21 (or of any
of its direct or indirect subsidiaries) to leave the employment of Vision 21;

                          ii)     act or serve, directly or indirectly, as a
principal, agent, independent contractor, consultant, director, officer,
employee, employer or advisor or in any other position or capacity with or for,
or acquire a direct or indirect ownership interest in or otherwise conduct
(whether as stockholder, partner, investor, joint venturer, or as owner of any
other type of interest), any Competing Management Business as such term is
defined herein; provided, however, that this clause (ii) shall not prohibit the
Physician or the Company from being the owner of up to 1% of any class of
outstanding securities of any company or entity if such class of securities is
publicly traded; or

                          iii)    directly or indirectly, either as principal,
agent, independent, contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's or the Company's
own benefit or for the benefit of any other person or entity, call upon or
solicit any customers or clients of the Management Business; provided however,
that the Physician may send out a general





                                    -60-
<PAGE>   61

notice to the customers or clients of the Management Business announcing the
termination of his arrangement with Vision 21 and may advertise in a general
manner without violating this covenant.  The parties hereto acknowledge and
agree that for purposes of this Section, patients which have in the past
received medical or optometric care from the Company or the Partnership and/or
shall in the future receive medical or optometric care from the New P.A. are
not deemed to be customers or clients of the Management Business.

                 b.       For the purposes of this Section 18.1, the following
terms shall have the meaning set forth below:

                          i)      "Management Business" shall mean management
and administration of the non-medical aspects of medical, ophthalmology and
optometry practices.

                          ii)     "Competing Management Business" shall mean an
individual, business, corporation, association, firm, undertaking, company,
partnership, joint venture, organization or other entity that either (A)
conducts a business substantially similar to the Management Business within the
State, or (B) provides or sells a service which is the same or substantially
similar to, or otherwise competitive with the services provided by the
Management Business within the State; provided, however, that "Competing
Management Business" shall not include Vision 21, or the Physician's internal
management and administration of the Physician's or the Company's medical
practice or participation in the management and administration of a physician
group in which the Physician or the Company devote a significant amount of time
to the practice of medicine.

                 c.       Should any portion of this Section 18.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Physician or the Company hereunder, and only in such event,
then the Physician, the Company and Vision 21 consent and agree to such
limitation on scope, duration or territory as may be finally adjudicated as
enforceable by a court of competent jurisdiction after the exhaustion of all
appeals.

                 d.       This covenant shall be construed as an agreement
ancillary to the other provisions of this Agreement, and the existence of any
claim or cause of action of the Physician or the Company against Vision 21,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Vision 21 of this covenant; provided, however,
that the Physician and the Company shall not be bound by this covenant and
shall not be obligated to pay the liquidated damages contemplated in this
Section 18.1 if at the time of a breach of this covenant the Business
Management Agreement has already been terminated pursuant to Section 6.2(a) or
6.2(d) thereof.  Without limiting other possible remedies to Vision 21 for
breach of this covenant, the Physician and the Company agree that injunctive or
other equitable relief will be available to enforce the covenants of this
provision.  The Physician, the Company and Vision 21 further expressly
acknowledge that the damages that would result from a violation of this
non-competition covenant would be impossible to predict with any degree of
certainty, and agree that liquidated damages in the amount of the aggregate
consideration received by the Physician pursuant to this





                                    -61-
<PAGE>   62

Agreement is reasonable in light of the severe harm to the Management Business
and Vision 21 which would result in the event that a violation of this
non-competition covenant were to occur.  For purposes of calculation of the
liquidated damages contemplated in this Section and for purposes of calculation
of the liquidated damages contemplated in the Business Management Agreement and
the Physician Employment Agreement between the Physician and the New P.A., the
aggregate consideration received by Physician and the Company pursuant to this
Agreement shall be in those amounts and in such form as set forth in Schedule
18.1.  If the Physician violates this non-competition covenant, Vision 21
shall, in addition to all other rights and remedies available at law or equity,
be entitled to (a) cancel the number of shares of Common Stock held by the
Physician or the Company or, with respect to shares of Common Stock entitled to
be received by the Physician or the Company, terminate its obligation to
deliver such number of shares of Common Stock valued as set forth in Section
6.6(a) of the Business Management Agreement, and (b) repayment by Physician to
Vision 21 of the fair market value as described above, of Vision 21 Common
Stock sold by Physician; but in no event shall Vision 21 be entitled to offset
amounts in excess of the liquidated damages sum pursuant to this Section 18.1.
The Physician and the Company agree to deliver to Vision 21 the certificates
representing any such shares canceled by Vision 21.  Payment and satisfaction
by Physician shall be made within sixty (60) days of notification to Physician
by Vision 21 that Physician has violated this non-competition covenant.

                 e.       Notwithstanding anything contained herein, this
Section 18.1 shall not be construed to (i) limit the freedom of any patient of
the Physician or the Company to choose the facility or physician from whom such
patient shall receive health-care services or (ii) limit or interfere with the
Physician's ability to exercise his professional medical judgment in treating
his patients or his ability to provide medical services to his patients.

         18.2.   Physician and Company Confidentiality Covenant.  From the date
hereof, the Physician and the Company shall not, directly or indirectly, use
for any purpose, other than in connection with the performance of the
Physician's duties under the Physician Employment Agreement with the New P.A.,
or disclose to any third party, any material information of Vision 21, the
Company or the Partnership, as appropriate (whether written or oral), including
any business management or economic studies, patient lists, proprietary forms,
proprietary business or management methods, marketing data, fee schedules, or
trade secrets of Vision 21, of the Company or of the Partnership, as
applicable, and including the terms and provisions of this Agreement and any
transaction or document executed by the parties pursuant to this Agreement.
Notwithstanding the foregoing, the Physician and the Company may disclose
information that the Physician or the Company can establish (a) is or becomes
generally available to and known by the public or medical community (other than
as a result of an unpermitted disclosure directly or indirectly by the
Physician or the Company or their respective Affiliates, advisors, or
representatives); (b) is or becomes available to the Physician or the Company
on a nonconfidential basis from a source other than Vision 21 or its
Affiliates, advisors or representatives, provided that such source is not and
was not bound by a confidentiality agreement with or other obligation of
secrecy to Vision 21 or its Affiliates, advisors or representatives of which
the Physician or the Company has knowledge; or (c) has already been or is
hereafter independently acquired or developed by the Physician or the





                                    -62-
<PAGE>   63

Company without violating any confidentiality agreement with or other
obligation of secrecy to Vision 21, the Company or their respective Affiliates,
advisors or representatives.  Without limiting the other possible remedies to
Vision 21 for the breach of this covenant, the Physician and the Company agree
that injunctive or other equitable relief shall be available to enforce this
covenant.  The Physician and the Company further agree that if any restriction
contained in this Section 18.2 is held by any court to be unenforceable or
unreasonable, a lesser restriction shall be enforced in its place and the
remaining restrictions contained herein shall be enforced independently of each
other.

         18.3.   Survival.  The parties acknowledge and agree that this Article
18 shall survive the Closing of the transactions contemplated herein.

         19.     DISPUTES.

         19.1.   Mediation and Arbitration.  Any dispute, controversy or claim
(excluding claims arising out of an alleged breach of Article 18 of this
Agreement) arising out of this Agreement, or the breach thereof, that cannot be
settled through negotiation shall be settled (a) first, by the parties trying
in good faith to settle the dispute by mediation under the Commercial Mediation
Rules of the AAA (such mediation session to be held in Tampa, Florida and to
commence within 15 days of the appointment of the mediator by the AAA), and (b)
if the controversy, claim or dispute cannot be settled by mediation, then by
arbitration administered by the AAA under its Commercial Arbitration Rules
(such arbitration to be held in Tampa, Florida, before a single arbitrator and
to commence within 15 days of the appointment of the arbitrator by the AAA),
and judgment on the award rendered by the arbitrator may be entered in any
court having jurisdiction thereof.

         20.     MISCELLANEOUS

         20.1.   Taxes.  Physician and the Company shall pay all transfer
taxes, sales and other taxes and charges, imposed by the State, if any, which
may become payable in connection with the transactions and documents
contemplated hereunder (excluding any of such taxes which may be attributable
to services to be provided by Vision 21 under the Business Management
Agreement).  Vision 21 shall pay all transfer taxes, sales and other taxes and
charges imposed by the State of Florida, if any, which may become payable in
connection with the transactions and documents contemplated hereunder
(excluding any of such taxes which may be attributable to services to be
provided by Vision 21 under the Business Management Agreement).

         20.2.   Remedies Not Exclusive.  No remedy conferred by any of the
specific provisions of this Agreement or any document contemplated by this
Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise.  The election of any one or more remedies by any party hereto shall
not constitute a waiver of the right to pursue other available remedies.

         20.3.   Parties Bound.  Except to the extent otherwise expressly
provided herein, this Agreement shall be binding upon and inure to the benefit

administrators, guardians, successors and assigns; and no other person shall
have any right, benefit or obligation hereunder.

of incorporation or organization of the respective entity shall govern.

         20.6.   Entire Agreement; Amendments and Waivers.  This Agreement,
together with the documents contemplated by this Agreement and all Exhibits and
Schedules hereto and thereto, constitute the entire agreement between the
parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof.
No supplement, modification or waiver of any of the provisions of this
Agreement shall be binding unless it shall be specifically designated to be a
supplement, modification or waiver of this Agreement and shall be executed in
writing by the party to be bound thereby.  No waiver of any of the provisions
of this Agreement shall be deemed or shall constitute a waiver of any other
provision hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver unless otherwise expressly provided.

         20.7.   Confidentiality Agreements.  The provisions of any prior
confidentiality agreements and letters of intent between or among Vision 21,
the Company, the Partnership and the Physician, as amended, shall terminate and
cease to be of any force or effect at and upon the Closing.

applicable jurisdiction, and including any subsequent revisions to, or judicial
interpretations of, those laws, in each case to the extent they are applicable
to this Agreement (the "Applicable Laws").  Accordingly, if the ownership of
any Nonmedical Asset by Vision 21 violates any Applicable Law, then the parties
hereto agree as follows: (a) the provisions of this Section 20.8 shall govern
and control; (b) if none of the parties hereto are materially economically
disadvantaged, then any Nonmedical Asset, the ownership of which violates any
Applicable Law, shall be deemed to have never been owned by Vision 21; (c) if
one or more of the parties hereto is materially economically disadvantaged,
then the parties hereto agree to negotiate in good faith such changes to the
structure and terms of the transactions provided for in this Agreement as may
be necessary to make these transactions, as restructured, lawful under
applicable laws and regulations, without materially disadvantaging either
party; (d) this Agreement shall be deemed modified and amended; and (e) the
parties to this Agreement shall execute and deliver all documents or
instruments necessary to effect or evidence the provisions of this Section

         20.9.   Assignment.  The Agreement may not be assigned by operation of
law or otherwise except that Vision 21 shall have the right to assign this
Agreement, at any time, to any Affiliate or direct or indirect wholly-owned
subsidiary.  In the event of such assignment, Vision 21 shall remain liable
hereunder.

         20.10.  Attorneys' Fees.  Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to
this Agreement or the other documents contemplated with respect to the
interpretation, enforcement or breach hereof, the prevailing party in such
action shall be entitled to an award of all reasonable costs of litigation or
arbitration, including, without limitation, attorneys' fees, to be paid by the
losing party, in such amounts as may be determined by the court having
jurisdiction of such action or proceeding, by the arbitrators deciding such
action or proceeding or as agreed to by the parties hereto.

         20.11.  Further Assurances.  From time to time hereafter and without
further consideration, each of the parties hereto shall execute and deliver
such additional or further instruments of conveyance, assignment and transfer
and take such other actions as any of the other parties hereto may reasonably
request in order to more effectively consummate the transactions contemplated
hereunder or as shall be reasonably necessary or appropriate in connection with
the carrying out of the parties' respective obligations hereunder for the
purposes of this Agreement.

         20.12.  Announcements and Press Releases.  Any press releases or any
other public announcements concerning this Agreement or the transactions
contemplated hereunder shall be approved in advance by Vision 21; provided,
however, that if Physician or the Company reasonably believes that he or it has
a legal obligation to make a press release and the consent Vision 21 cannot be
obtained, then the release may be made without such approval.

         20.13.  No Tax Representations.  Each party acknowledges that it is
relying solely on its advisors to determine the tax consequences of the
transactions contemplated hereunder and that no representation or warranty has
been made by any party as to the tax consequences of such transactions except
as otherwise specifically set forth in this Agreement.

         20.14.  No Rights as Stockholder.  The Physician shall have no rights
as a stockholder with respect to any shares of Common Stock until the issuance
of a stock certificate evidencing such shares.  Except as otherwise provided in
the Agreement, no adjustment shall be made for dividends or distributions or
other rights for which the record date is prior to such date any stock
certificate is issued.

         20.15.  Multiple Counterparts.  This Agreement may be executed in one

                            ASSET PURCHASE AGREEMENT

         This Asset Purchase Agreement (this "Agreement"), effective as of
September 1, 1997, is by and among LEONARD E. CORTELLI, M.D., P.A., a Florida
professional association (the "Company"), LEONARD E. CORTELLI, M.D. (the
"Physician"), and VISION TWENTY-ONE, INC., a Florida corporation ("Vision 21").

                                 R E C I T A L S

         A.       Physician is a physician licensed to practice medicine in the
State (as defined herein) and currently employs ophthalmologists and conducts an
ophthalmology practice through the Company and through optometrist employees
currently conducts an optometry practice through the Company.

         B.       Physician owns all of the issued and outstanding shares of
capital stock of the Company.

         C.       Vision 21 provides business management services and facilities
for eye care professionals and related businesses.

         D.       The Company is a partner with Florida Eye Center, Sever &
Ramseur, M.D., P.A., a Florida professional association ("Sever & Ramseur,
P.A."), and Thomas J. Pusateri, M.D., P.A., a Florida professional association
("Pusateri, P.A."), in a Florida partnership known as Florida Eye Center (the
"Partnership").

         E.       Simultaneously herewith, the Partnership shall distribute all
of its assets and assign all of its liabilities to Pusateri, P.A., the Company
and Sever & Ramseur, P.A.

         F.       Following such transfers and assignments by the Partnership,
Vision 21 intends to purchase, assume and acquire all of the Company's, Sever &
Ramseur, P.A.'s and Pusateri, P.A.'s respective assets to the extent provided by
law and to assume certain liabilities of the Company, Sever & Ramseur, P.A. and
Pusateri, P.A., in exchange for capital stock of Vision 21 and other
consideration, all as more specifically provided herein.

         G.       The Company desires to sell, assign and transfer all of its
assets to the extent permitted by law to Vision 21 and to have Vision 21 assume

conditions of this Agreement.

         H.       Vision 21 cannot acquire certain of the Company's, Sever &
Ramseur, P.A.'s or Pusateri, P.A.'s respective assets because of laws
prohibiting general business corporations from engaging in the practice of
medicine or optometry, exercising control over physicians practicing medicine or
optometrists practicing optometry, or engaging in certain practices such as fee
splitting with physicians or optometrists.

seventy-five (75) days of the Closing Date conduct an audit of the Company and
the Partnership to ensure that the Company and the Partnership have collected

the audit reveals that the Company and/or the Partnership have (a) collected
accounts receivable at an accelerated rate during such period, or (b) paid
accounts payable at a reduced or delayed rate during such period, Vision 21
shall seek an adjustment to the Purchase Price. In the event that the proposed

transaction, the proposed adjustment shall take into account the related impact
upon net income created by the change in amortization of such goodwill. Vision
21 shall notify the Physician in writing within seventy-five (75) days of the
Closing Date of its decision to seek an adjustment of the Purchase Price, the
amount of the proposed adjustment and its reasons for such decision. If
Physician does not notify Vision 21 within ten (10) days of Physician's receipt
of such notice that Physician objects to the proposed adjustment, then the
proposed adjustment shall take place and shall be final. If Physician notifies
Vision 21 within the above-described ten (10) day period that Physician objects
to the proposed adjustment, then Vision 21 and Physician shall in good faith
negotiate an appropriate amount of the adjustment, if any, which should be made.
During all time periods following Vision 21's notice that it intends to adjust
the Purchase Price until the adjustment is finalized, Vision 21 shall provide to
Physician and his accountants full access to all relevant books, records and
work papers utilized in preparing the proposed Purchase Price adjustment. The
adjustment may be settled in cash (which shall be set-off from moneys due New
P.A. pursuant to the Business Management Agreement) or Vision 21 Common Stock at
the Physician's option.

         2.7.     Subsequent Actions. If, at any time after the Closing Date,

that would justify the exercise of such a right; and (ii) none of the Company,
the Partnership or the Physician currently contemplates, or has reason to

the Company, the Partnership or the Physician has received any notice or other
communication from any issuer of any Insurance Policy cancelling such policy,
materially increasing any deductibles or retained amounts thereunder, and to the
actual knowledge of the Company, no such cancellation or increase of
deductibles, retainages or premiums is threatened. Except as set forth on
Schedule 3.13, none of the Company, the Partnership, the Physician or any
Professional Employee has any outstanding claims, settlements or premiums owed
against any Insurance Policy, and the Company, the Partnership, the Physician

use thereof by Vision 21 upon consummation of the transactions contemplated
hereby and the Proprietary Rights are freely transferable. No claim has been

         5.11.    Compliance with Laws. Vision 21 has not failed to comply with
any applicable laws, regulations and licensing requirements or failed to file
with the proper authorities any necessary statements and reports except where
the failure to so comply or file would not, individually or in the aggregate,
have a material adverse effect on the Transaction. There are no existing
violations by Vision 21 of any federal, state or local law or regulation that
could, individually or in the aggregate, have a material adverse effect on the
Transaction. Vision 21 possesses all necessary licenses, franchises, permits and
governmental authorizations for the conduct of Vision 21's business as now
conducted and after the Closing, as contemplated in this Agreement and the
Business Management Agreement, except for such licenses, franchises, permits or
governmental authorizations which, if not possessed by Vision 21, would not have
a material adverse effect on the business of Vision 21. The transactions
contemplated by this Agreement will not result in a default under or a breach or
violation of, or adversely affect the rights and benefits afforded by any such
licenses, franchises, permits or government authorizations, except for any such
default, breach or violation that would not, individually or in the aggregate,
have a material adverse effect on the Transaction or the performance of the
services contemplated under the Business Management Agreement. Since January 1,
1993, Vision 21 has not received any notice from any federal, state or other
governmental authority or agency having jurisdiction over its properties or
activities, or any insurance or inspection body, that its operations or any of
its properties, facilities, equipment, or business practices fail to comply with
any applicable law, ordinance, regulation, building or zoning law, or
requirement of any public or quasi-public authority or body, except where
failure to so comply would not, individually or in the aggregate, have a
material adverse effect on the Transaction.

         5.12.    Insolvency Proceedings.  Vision 21 is not currently under the
jurisdiction of a Federal or state court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

         5.13.    Employment of Company's Employees. Vision 21 does not
currently intend to change the existing composition or employment terms of any
of the non-professional personnel which have employment arrangements with the
Company or the Partnership on the effective date of this Agreement (except as is
necessary for Vision 21 to employ such individuals pursuant to the Business
Management Agreement). Vision 21 reserves the right, however, to change the
number, composition or employment terms of such non-professional personnel in
the future.

                  a.       Physician understands that the Securities will not be

predicated in part on the Physician's representations, warranties, covenants and

a nominee or agent, and without a view to resale or other distribution within

except as contemplated in this Agreement, and that Physician will not distribute
any of the Securities in violation of the Securities Act. All Securities shall

         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

set forth below Physician's name on Schedule 6.1(d) is Physician's principal
residence.

                  e.       Physician (i) acknowledges that the Securities issued
to Physician at the Closing must be held indefinitely by Physician unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that in
such cases where the Rule is not applicable, compliance with some other

currently available for use by Physician for resale of any of the Securities to
be acquired by Physician upon consummation of the transactions described in this
Agreement.

                  f.       Physician represents and warrants to Vision 21 that
Physician, either alone or together with the assistance of Physician's own
professional advisor, has such knowledge and experience in financial and
business matters such that Physician is capable of evaluating the merits and
risks of Physician's investment in any of the Securities to be acquired by
Physician upon consummation of the transactions described in this Agreement.

                  g.       Physician confirms that Physician has had the
opportunity to ask questions of and receive answers from Vision 21 concerning
the terms and conditions of Physician's investment in the Securities, and the
Physician has received to Physician's satisfaction, such additional information,
in addition to that set forth herein, about Vision 21's operations and the terms
and conditions of the offering as Physician has requested.

                  h.       In order to ensure compliance with the provisions of
paragraph (c) hereof, Physician agrees that after the Closing Physician will not
sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the Securities Act) without first
complying with either of the following conditions, the expenses and costs of
satisfaction of which shall be fully borne and paid for by Physician:

                           i)       Vision 21 shall have received a written 
legal opinion from legal counsel, which opinion and counsel shall be
satisfactory to Vision 21 in the exercise of its reasonable judgment, or a copy
of a "no-action" or interpretive letter of the Securities and Exchange
Commission specifying the nature and circumstances of the proposed transfer and
indicating that the proposed transfer will not be in violation of any of the
registration provisions of the Securities Act and the rules and regulations
promulgated thereunder; or

                           ii)      Vision 21 shall have received an opinion
from its own counsel to the effect that the proposed transfer will not be in
violation of any of the registration provisions of the Securities Act and the
rules and regulations promulgated thereunder.

Physician also agrees that the certificates or instruments representing the
Securities to be issued to Physician pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this Section
and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 6.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.

                  i.       Physician understands that there can be no assurance
that a Public Offering by Vision 21 will ever occur or if it does occur that it
will be successful.

                                      -37-

                  j.       Physician agrees that he shall be considered an
"affiliate" of Vision 21 for purposes of Rule 144 and agrees to the restrictions
and limitations imposed by Rule 144 on affiliates. Physician further agrees that
he shall be considered an affiliate of Vision 21 for Rule 144 purposes even if
he does not meet the technical definition of "affiliate" under Rule 144.

         6.2.     Current Public Information. At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act, as
such Rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC) regarding the availability of current public
information to the extent required to enable any holder of shares of Common
Stock to sell such shares without registration under the Securities Act pursuant
to Rule 144 (or any similar rule or regulation).

         7.       CLOSING DATE REPRESENTATIONS AND WARRANTIES OF THE
PHYSICIAN. The Physician represents and warrants that, except as disclosed in
the Schedules, the following will be true and correct on the Closing Date as if

         7.2.     Capitalization. The authorized capital stock of New P.A.
consists of _____ shares of New P.A. Common Stock, of which _____ shares are
issued and outstanding, and no shares of capital stock of New P.A. are held in

shareholders' agreements. The Company separately owns _____ of such shares of
New P.A. common stock. Each outstanding share of New P.A.'s common stock has
been legally and validly issued and is fully paid and nonassessable. Except as
set forth on Schedule 7.2, there exist no options, warrants, subscriptions or
other rights to purchase, or securities convertible into or exchangeable for,
any of the authorized or outstanding securities of New P.A. No shares of capital

<PAGE>   39

Vision 21 are true, correct and complete copies thereof, as in effect on the
Closing Date. The minute books of New P.A., copies of which have been delivered
or made available to Vision 21, contain accurate minutes of all meetings of, and
accurate consents to all actions taken without meetings by, the Board of
Directors (and any committees thereof) and the stockholders of New P.A. since

performance by New P.A. of the Business Management Agreement, the Physician
Employment Agreements, the Optometrist Employment Agreements and the other
agreements contemplated thereby, and the consummation of the transactions and
provisions of services contemplated thereby, have been duly authorized by New
P.A. The Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements and each other agreement contemplated thereby
will be as of the Closing Date duly executed and delivered by New P.A. and will
constitute legal, valid and binding obligations of New P.A. enforceable against
New P.A. in accordance with their respective terms, except as may be limited by
applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally or the availability of equitable remedies.

         7.5.     No Violation. Neither the execution, delivery or performance
of the Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements or the other agreements contemplated thereby
nor the consummation of the transactions or provision of services contemplated
thereby will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the Articles or
Certificate of Incorporation or Bylaws of New P.A., or (b) to the actual
knowledge of the Physician, violate or conflict with any judgment, decree,
order, statute, rule or regulation of any court or any public, governmental or
regulatory agency or body.

         7.6.     No Business, Agreements, Assets or Liabilities.  New P.A. has

Certificate of Incorporation and Bylaws, and as of the Closing Date, the
Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements, the Employee Benefit Plans and the other
contracts or agreements listed on Schedule 7.6, New P.A. is not a party to or
subject to any agreement, indenture or other instrument. New P.A. does not own
any assets (tangible or intangible) other than the consideration received upon
the issuance of shares of capital stock and New P.A. does not have any
liabilities, accrued, contingent or otherwise (known or unknown and asserted or
unasserted).

         7.7.     Compliance with Laws. New P.A. has complied with all
applicable laws, regulations and licensing requirements and has filed with the
proper authorities all necessary statements and reports, except where failure to
so comply or file would not, individually or in the aggregate, have a material
adverse effect on the business, operations or financial condition of New P.A.

         8.       COVENANTS OF THE COMPANY AND THE PHYSICIAN. The Company and
the Physician, jointly and severally, agree that between the date hereof and the

Company shall, together with Pusateri, P.A. and Sever & Ramseur, P.A., form,
organize and incorporate New P.A. in the State and the Articles or Certificate
of Incorporation and Bylaws of New P.A. shall be in form and substance
reasonably satisfactory to Vision 21. The Company shall not permit New P.A. to

shall take all actions and execute all documents, agreements or instruments
necessary to transfer to New P.A. the Company's and the Partnership's medical

and the Physician shall cause, at or immediately prior to Closing, each
Physician Employee (except for those non-shareholder Physician Employees
identified on Schedule 8.16) who is then an employee of the Company or the
Partnership and Physician agrees at or immediately prior to Closing (i) to
terminate his employment agreement, if any, with the Company or the Partnership
by mutual consent without any liability therefor on the part of the Company or
the Partnership, and (ii) to enter into a new Physician Employment Agreement
with the New P.A. in accordance with the terms of the Business Management
Agreement.

         8.17.    Optometrist Employment Agreements. The Company, the
Partnership and the Physician shall cause, at or immediately prior to Closing,
each Optometrist Employee who is then an employee of the Company (i) to
terminate his existing employment agreement, if any, with the Company or the
Partnership by mutual consent without any liability therefor on the part of the
Company, and (ii) to enter into a new Optometrist Employment Agreement with the

         8.18.    Termination of Retirement Plans. Prior to Closing, the

to take all steps necessary to discontinue benefits accruals under any Employee
Benefit Plan that is intended to be a qualified employee retirement plan under
Section 401(a) of the Code (a "Retirement Plan") effective as of Closing or as
soon thereafter as may be practical. Effective at the time of Closing, the
Company and the Partnership shall cause New P.A. to assume all of the
obligations of the Company and the


                                      -43-

<PAGE>   44

Partnership as the sponsoring employer and/or plan administrator of the
Retirement Plan in compliance with applicable law.

                  Subsequent to Closing, the New P.A. and Vision 21 shall review
the extent to which the New P.A. can resume contributions to the Retirement Plan
without violating the qualification requirements of Sections 410(b) and
401(a)(4) of the Code, taking into account any employees of Vision 21 who would
be "leased employees" of the New P.A. under Section 414(n) of the Code. If
Vision 21 and the New P.A. mutually agree that such qualification requirements
can be satisfied, the Company may elect to continue the Retirement Plan and make
contributions in accordance with its terms, provided that the New P.A. shall
agree to cover at its own expense any Vision 21 employees who are leased
employees if such coverage is required to maintain the tax-qualified status of
the Retirement Plan.

         8.19.    Delivery of Schedules.  The Company and the Physician shall
deliver to Vision 21 all Schedules required to be delivered by them prior to the
Closing.

         8.20.    Assignment of Fees for Medical and Optometry Services. On or
prior to the Closing Date, the Company shall obtain an irrevocable assignment
from all Professional Employees of any and all of their rights to receive
payment for the provision of ophthalmology or optometry services which are part
of the Accounts Receivable to Vision 21 existing on the Closing Date, except for
those fees specified and set forth on Schedule 8.20. Each Professional Employee
shall undertake to endorse any payments received on account of such services to
the order of Vision 21 and to take such other action as may be necessary to
confirm to Vision 21 the rights to collect and retain for its own account such
Accounts Receivable. The Company shall cause its Professional Employees to agree
that such security interest of such lender(s) is intended to be a first priority
security interest and is superior to any right, title or interest which may be
asserted by such Professional Employees with respect to the Accounts Receivable
or the proceeds thereof. In the event that the assignment of rights described in
this Section shall be deemed, for any reason, to be ineffective as an outright
assignment, the Company shall cause each Professional Employee to agree that
such Professional Employee shall be deemed, effective as of the Closing Date, to
have granted to Vision 21 a first priority lien on and security interest in and
to any and all interests of such Professional Employee in any of the Accounts
Receivable, and all proceeds with respect thereto, to secure the collection by
Vision 21 of all Accounts Receivable, and this Agreement shall be deemed to be a
security agreement to the extent necessary to give effect to the foregoing. The
Company shall cause each Professional Employee to execute and deliver, all such
financing statements as the Company or Vision 21 may request in order to perfect
such security interest. The Company shall not suffer any Professional Employee
to grant any other lien on or security interest in or to such Accounts
Receivable or any proceeds thereof.

         9.       COVENANTS OF VISION 21.  Vision 21 agrees that between the
date hereof and the Closing:


                                      -44-

<PAGE>   45

         9.1.     Consummation of Agreement. Vision 21 shall use its best
efforts to cause the consummation of the transactions contemplated hereby in
accordance with their terms and conditions and take all corporate and other
actions necessary to approve the Transaction; provided, however, that this
covenant shall not require Vision 21 to make any expenditures that are not
expressly set forth in this Agreement or otherwise contemplated herein.

         9.2.     Notification of Certain Matters. Vision 21 shall promptly
inform the Company and the Physician in writing of (a) any notice of, or other
communication relating to, a default or event that, with notice or lapse of time
or both, would become a default, received by Vision 21 subsequent to the date of
this Agreement and prior to the Closing Date under any agreement or commitment
entered into by Vision 21 material to Vision 21's condition (financial or
otherwise), operations, assets, liabilities or business and to which it is
subject; or (b) any material adverse change in Vision 21's condition (financial
or otherwise), operations, assets, liabilities or business.

         9.3.     Licenses and Permits.  Vision 21 shall use its best efforts to
obtain all licenses, permits, approvals or other authorizations required under
any law, statute, rule, regulation or ordinance, or otherwise necessary or
desirable to consummate the Transaction or provide the services contemplated by
the Business Management Agreement and to conduct the intended business of Vision
21.

         9.4.     Release of Physician From Practice Liabilities. Vision 21
shall use its best efforts to obtain from third party creditors the release of
Physician from any personal liabilities relating to the Practice which are
identified on Schedule 9.4 and assumed by Vision 21 pursuant to the terms of
this Agreement.

         9.5.     Approvals of Third Parties.  Vision 21 shall use its best
efforts to secure, as soon as practicable after the date hereof, all necessary
approvals and consents of third parties to the consummation of the transactions
contemplated hereby.

         10.      COVENANTS OF VISION 21, THE COMPANY AND THE PHYSICIAN. Vision
21, the Company and the Physician agree as follows (with respect to New P.A.'s
covenants, the Physician agrees to cause New P.A. to perform, and with respect
to the Partnership's covenants, the Company agrees to use its best efforts to
cause the Partnership to perform):

         10.1.    Amendment of Schedules. Each party hereto agrees that, with
respect to the representations and warranties of such party contained in this
Agreement, such party shall have the continuing obligation until the Closing to
attach, supplement or amend promptly the Schedules with respect to any matter
that would have been or would be required to be set forth or described in the
Schedules in order to not materially breach any representation, warranty or
covenant of such party contained herein; provided that no amendment or
supplement to a Schedule that constitutes or reflects a material adverse change
to the Company, the Partnership or the Nonmedical Assets may be made unless
Vision 21 consents to such amendment or supplement, and no amendment or
supplement to a Schedule that constitutes or reflects a material adverse change
to Vision 21 may be


                                      -45-
<PAGE>   46

made unless the Company and the Physician consent to such amendment or
supplement. For all purposes of this Agreement, including without limitation for
purposes of determining whether the conditions set forth in Sections 11.1 and
12.1 have been fulfilled, the Schedules hereto shall be deemed to be the
Schedules as amended or supplemented pursuant to this Section 10.1. In the event
that the Company is required to amend or supplement a Schedule in accordance
with this Section 10.1 and Vision 21 does not consent to such amendment or
supplement, or Vision 21 is required to amend or supplement a Schedule in
accordance with this Section 10.1 and the Company and the Physician do not
consent, this Agreement shall be deemed terminated by mutual consent as set
forth in Section 16.1(d) or Section 16.1(e) as appropriate.

         10.2.    Fees and Expenses.

                  a.       If the Transaction is consummated, Vision 21 shall
pay all costs of the Audit of the Partnership's Financial Statements and
financial records by the Accountants (or auditors designated by Vision 21's
Accountants). All items prepared by the Accountants in connection with the Audit
("Prepared Audit Materials") shall be for use solely by Vision 21; provided,
however, that the Company may utilize the Prepared Audit Materials solely in
connection with its review of Vision 21's calculation of the Purchase Price. The
Prepared Audit Materials shall not be deemed to include those items which
customarily remain the property of auditors such as their working papers and
memos.

                  b.       In the event the Transaction is not consummated,
Vision 21 shall pay for all of the expenses of the Accountants in connection
with the Audit. The Company, Physician, Pusateri, P.A. and Sever & Ramseur,

<PAGE>   54

the Partnership or New P.A. required to be stated therein or necessary to make
the statements therein not misleading, and not provided to Vision 21 or its
counsel by the Company or the Physician, provided, however, that such indemnity
shall not inure to the benefit of Vision 21 to the extent that such untrue
statement (or alleged untrue statement) was made in, or omission (or alleged
omission) occurred in, any preliminary prospectus, and such information was not
so included by Vision 21 and properly delivered to shareholders of Vision 21 who
acquire Vision 21 Common Stock in any Public Offering;

                  c.       any filings, reports or disclosures made pursuant to

                  a.       a breach by Vision 21 of any representation, warranty
or covenant of Vision 21 contained therein or in any schedule or certificate
delivered hereunder;

                  b.       any liability under the Securities Act, the Exchange

                  c.       any filings, reports or disclosures made pursuant to

         Notwithstanding anything in this Section 15.2, Vision 21 shall not be
liable for any Damages resulting from any matter not disclosed to Vision 21 by
any of the third parties acquired by Vision 21 in connection with the Recent

         15.3.    Conditions of Indemnification.  All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                  a.       A party claiming indemnification under this Agreement
(an "Indemnified Party") shall promptly (and, in any event, at least ten (10)
days prior to the due date for any responsive pleadings, filings or other
documents) (i) notify the party from whom indemnification


                                      -54-


<PAGE>   55

is sought (the "Indemnifying Party") of any third-party claim or claims asserted
against the Indemnified Party ("Third Party Claim") that could give rise to a
right of indemnification under this Agreement and (ii) transmit to the
Indemnifying Party a written notice ("Claim Notice") describing in reasonable
detail the nature of the Third Party Claim, a copy of all papers served with
respect to such claim (if any), an estimate of the amount of damages
attributable to the Third Party Claim and the basis of the Indemnified Party's
request for indemnification under this Agreement. Except as set forth in Section
15.6, the failure to promptly deliver a Claim Notice shall not relieve the
Indemnifying Party of its obligations to the Indemnified Party with respect to
the related Third Party Claim except to the extent that the resulting delay is
materially prejudicial to the defense of such claim. Within thirty (30) days
after receipt of any Claim Notice (the "Election Period"), the Indemnifying
Party shall notify the Indemnified Party (i) whether the Indemnifying Party
disputes its potential liability to the Indemnified Party under this Article 15
with respect to such Third Party Claim and (ii) whether the Indemnifying Party
desires, at the sole cost and expense of the Indemnifying Party, to defend the
Indemnified Party against such Third Party Claim.

                  b.       If the Indemnifying Party notifies the Indemnified
Party within the Election Period that the Indemnifying Party elects to assume
the defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 15.3(b). The Indemnifying
Party shall have full control of such defense and proceedings, including any
compromise or settlement thereof. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is entitled to indemnification hereunder), to file, during the Election
Period, any motion, answer or other pleadings that the Indemnified Party shall
deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being
understood and agreed that if an Indemnified Party takes any such action that is
prejudicial and causes a final adjudication that is adverse to the Indemnifying
Party, the Indemnifying Party shall be relieved of its obligations hereunder
with respect to such Third Party Claim). If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to
Section 15.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially


                                      -55-

<PAGE>   56

similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys at any time for the
Indemnified Party, which firm shall be designated in writing by the Indemnified
Party.

                  c.       If the Indemnifying Party fails to notify the 
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 15.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
15.3(b) but fails diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party (if the Indemnified Party is entitled
to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 15 and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnifying Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control any defense or settlement controlled by the
Indemnified Party pursuant to this Section 15.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

                  d.       In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 19.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  e.       Payments of all amounts owing by an Indemnifying
Party pursuant to this Article 15 relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim or (iii) the expiration of the period for
appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by an
Indemnifying Party pursuant to Section 15.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the sixty (60) day Indemnity
Notice period or (ii) the expiration of the period for appeal, if any, of a
final adjudication or arbitration of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

         15.4.    Remedies Not Exclusive.  The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity. This Article 15
regarding indemnification shall survive Closing.

         15.5.    Costs, Expenses and Legal Fees. Each party hereto agrees to
pay the costs and expenses (including attorneys' fees and expenses) incurred by
the other parties in successfully (a) enforcing any of the terms of this
Agreement, or (b) proving that another party breached any of the terms of this
Agreement.

         15.6.    Indemnification Limitations. Notwithstanding the provisions of
Sections 15.1 and 15.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2., 3.3, 3.11, 3.14,
4.3, 4.5, 4.7, 5.1, 5.2, 5.3, 5.4 and 6.1 may be made at any time, and a claim
for indemnification for a breach of the representations and warranties contained
in Sections 3.9, 3.15, 3.17, 3.18, 3.24, 3.25, 3.26, 3.27, 3.28, 3.30, 4.1, 4.4,
4.6, 5.6 and 5.7 may be made at any time within the applicable statute of
limitations; (b) indemnification based upon Sections 15.1(b) through (d) and
15.2(b) may be made at any time within the applicable statute of limitations;
and (c) the Physician shall not be required to indemnify Vision 21 pursuant to
Section 15.1 unless, and to the extent that, the aggregate amount of Damages
incurred by Vision 21 shall exceed an amount equal to two percent (2%) of the
total Purchase Price; and (c) the Physician shall not be required to indemnify
Vision 21 with respect to a breach of a representation, warranty or covenant for
Damages in excess of the aggregate Purchase Price received by the Physician
(other than pursuant to a requirement to indemnify Vision 21 under Sections 3.27
or 3.28, or unless the breach involves an intentional breach or fraud by the
Physician which shall be unlimited).

         15.7. Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds and such correlative insurance
benefit shall be net of the insurance premium, if any, that becomes due as a
result of such claim.

         15.8. Payment of Indemnification Obligation. In the event that the
Physician has an indemnification obligation to Vision 21 hereunder, subject to
Vision 21's approval as set forth below, the Physician may satisfy such
obligation by transferring to Vision 21 such number of shares of Vision 21
Common Stock owned by the Physician having an aggregate fair market value (which
is the fair market value at such time based on the last reported sale price of
Vision 21 Common Stock on a principal national securities exchange or other
exchange on which the Vision 21 Common Stock is then listed or the last quoted
ask price on any over-the-counter market through which the Vision 21 Common
Stock is then quoted on the last trading day immediately preceding the day on
which the Physician transfers shares of Vision 21 Common Stock to Vision 21
hereunder) equal to the indemnification obligation, provided that each of the
following conditions are satisfied:

                  a.       The Physician shall transfer to Vision 21 good,
valid and marketable title to the shares of Vision 21 Common Stock, free and
clear of all adverse claims, security interests, liens, claims, proxies,
options, stockholders' agreements and encumbrances;

                  b.       The Physician shall make such representation and
warranties as to title to the stock, absences of security interests, liens,
claims, proxies, stockholders' agreements and other encumbrances and other
matters as reasonably requested by Vision 21; and

                  c.       The other terms and conditions of any transaction
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21.

         16.      TERMINATION.

         16.1.    Termination.  This Agreement may be terminated and the
Transaction may be abandoned:

                  a.       at any time prior to the Closing Date by mutual
 agreement of all parties;

                  b.       at any time prior to the Closing Date by Vision 21 if
any representation or warranty of the Company or the Physician contained in this
Agreement or in any certificate or other document executed and delivered by the
Company or the Physician pursuant to this Agreement is or becomes untrue or
breached in any material respect or if the Company or the Physician fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt of written notice thereof;

                  c.       at any time prior to the Closing Date by the Company
if any representation or warranty of Vision 21 contained in this Agreement is or
becomes untrue in any material respect or if Vision 21 fails to comply in any
material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt or written notice thereof;


                                      -58-

<PAGE>   59

                  d.       at any time prior to the Closing Date by the Company
in the event of the failure of any of the conditions precedent set forth in
Article 12 of this Agreement;

                  e.       at any time prior to the Closing Date by Vision 21 in
the event of the failure of any of the conditions precedent set forth in Article
11 of this Agreement;

                  f.       by Vision 21 if at any time prior to the Closing
Date, Vision 21 deems termination to be advisable, provided, however, that if
Vision 21 exercises its right to terminate this Agreement under this
subsection, Vision 21 shall reimburse the Company and the Physician for all
reasonable attorneys' and accountants' fees incurred by the Company and the
Physician in connection with this Agreement; provided that Vision 21 shall only
reimburse the Company and the Physician up to an aggregate maximum amount of
One Hundred Thousand and No/100 Dollars ($100,000.00) for such fees; or

                  g.       by Vision 21 or the Company if the Transaction shall
not have been consummated by November 30, 1997.

         16.2.    Effect of Termination. In the event this Agreement is
terminated pursuant to Section 16.1, Vision 21, the Company and the Physician,
shall each be entitled to pursue, exercise and enforce any and all remedies,
rights, powers and privileges available at law or in equity, subject to the
limitations set forth in Section 15.1. In the event of a termination of this
Agreement under the provisions of this Article 16, a party not then in material
breach of this Agreement shall stand fully released and discharged of any and
all obligations under this Agreement.

         17.      PHYSICIAN EMPLOYMENT AGREEMENT.

         17.1.    Physician Employment Agreement. The parties acknowledge that
in accordance with the terms of this Agreement, Physician, as employee, and the
New P.A., as employer, have entered into the Physician Employment Agreement and
that Vision 21 is entitled to enforce such Physician Employment Agreement as an
intended third party beneficiary. Physician and Vision 21 acknowledge that
Vision 21 would suffer severe harm in the event of Physician's resignation prior
to the expiration of the five (5) year term of such Physician Employment
Agreement (without first obtaining the written consent of Vision 21) or a breach
or default of Physician's obligations under such Physician Employment Agreement,
and Physician, the Company and Vision 21 agree that Vision 21 shall be entitled
to recover from Physician any and all damages incurred by Vision 21 caused by
such resignation, breach or default. Notwithstanding the foregoing, Vision 21
shall not be entitled to recover its damages caused by such resignation, breach
or default if such resignation, breach or default was caused by: (i) the death
or disability of Physician, (ii) circumstances not caused by an act or omission
of Physician and which circumstances are beyond his control, or (iii) loss of
Physician's license to practice as an ophthalmologist, unless such loss of
license is due to an act or omission of Physician. Notwithstanding the
foregoing, Physician shall have no obligation to pay the damages contemplated in
this Section 17.1 if (a) the Business Management Agreement has been terminated
pursuant to a material breach by Vision 21, or (b) Physician cures any such
breach


                                      -59-
<PAGE>   60

or default of the Physician Employment Agreement within a period of thirty (30)
days after notice from Vision 21 of such breach or default.

         17.2.    Survival.  The parties acknowledge and agree that this Article
17 shall survive the Closing of the transactions contemplated herein.

         18.      NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

         18.1.    Physician and Company Non-Competition Covenant.

                  a.       The Physician and the Company recognize that the
covenants of the Physician and the Company contained in this Section 18.1 are an
essential part of this Agreement and that, but for the agreement of the
Physician and the Company to comply with such covenants, Vision 21 would not
have entered into this Agreement. The Physician and the Company acknowledge and
agree that the Physician's and the Company's covenants not to compete are
necessary to ensure the continuation of the Management Business (as defined
below) and are necessary to protect the reputation of Vision 21, and that
irreparable and irrevocable harm and damage will be done to Vision 21 if the
Physician or the Company compete with the Management Business or Vision 21. The
Physician and the Company accordingly agree that for the periods set forth in
the Business Management Agreement the Physician and the Company shall not:

                           i)       directly or indirectly, either as principal,
agent, independent contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's or the Company's
own benefit or for the benefit of any other person or entity knowingly (A) hire,
attempt to hire, contact or solicit with respect to hiring any employee of
Vision 21 (or of any of its direct or indirect subsidiaries) or (B) induce or
otherwise counsel, advise or encourage any employee of Vision 21 (or of any of
its direct or indirect subsidiaries) to leave the employment of Vision 21;

                           ii)      act or serve, directly or indirectly, as a
principal, agent, independent contractor, consultant, director, officer,
employee, employer or advisor or in any other position or capacity with or for,
or acquire a direct or indirect ownership interest in or otherwise conduct
(whether as stockholder, partner, investor, joint venturer, or as owner of any
other type of interest), any Competing Management Business as such term is
defined herein; provided, however, that this clause (ii) shall not prohibit the
Physician or the Company from being the owner of up to 1% of any class of
outstanding securities of any company or entity if such class of securities is
publicly traded; or

                           iii)     directly or indirectly, either as principal,
agent, independent, contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's or the Company's
own benefit or for the benefit of any other person or entity, call upon or
solicit any customers or clients of the Management Business; provided however,
that the Physician may send out a general


                                      -60-

<PAGE>   61

notice to the customers or clients of the Management Business announcing the
termination of his arrangement with Vision 21 and may advertise in a general
manner without violating this covenant. The parties hereto acknowledge and agree
that for purposes of this Section, patients which have in the past received
medical or optometric care from the Company or the Partnership and/or shall in
the future receive medical or optometric care from the New P.A. are not deemed
to be customers or clients of the Management Business.

                  b.       For the purposes of this Section 18.1, the following
terms shall have the meaning set forth below:

                           i)       "Management Business" shall mean management
and administration of the non-medical aspects of medical, ophthalmology and
optometry practices.

                           ii)      "Competing Management Business" shall mean
an individual, business, corporation, association, firm, undertaking, company,
partnership, joint venture, organization or other entity that either (A)
conducts a business substantially similar to the Management Business within the
State, or (B) provides or sells a service which is the same or substantially
similar to, or otherwise competitive with the services provided by the
Management Business within the State; provided, however, that "Competing
Management Business" shall not include Vision 21, or the Physician's internal
management and administration of the Physician's or the Company's medical
practice or participation in the management and administration of a physician
group in which the Physician or the Company devote a significant amount of time
to the practice of medicine.

                  c.       Should any portion of this Section 18.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Physician or the Company hereunder, and only in such event,
then the Physician, the Company and Vision 21 consent and agree to such
limitation on scope, duration or territory as may be finally adjudicated as
enforceable by a court of competent jurisdiction after the exhaustion of all
appeals.

                  d.       This covenant shall be construed as an agreement
ancillary to the other provisions of this Agreement, and the existence of any
claim or cause of action of the Physician or the Company against Vision 21,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Vision 21 of this covenant; provided, however,
that the Physician and the Company shall not be bound by this covenant and shall
not be obligated to pay the liquidated damages contemplated in this Section 18.1
if at the time of a breach of this covenant the Business Management Agreement
has already been terminated pursuant to Section 6.2(a) or 6.2(d) thereof.
Without limiting other possible remedies to Vision 21 for breach of this
covenant, the Physician and the Company agree that injunctive or other equitable
relief will be available to enforce the covenants of this provision. The
Physician, the Company and Vision 21 further expressly acknowledge that the
damages that would result from a violation of this non-competition covenant
would be impossible to predict with any degree of certainty, and agree that
liquidated damages in the amount of the aggregate consideration received by the
Physician pursuant to this



                                      -61-
<PAGE>   62

Agreement is reasonable in light of the severe harm to the Management Business
and Vision 21 which would result in the event that a violation of this
non-competition covenant were to occur. For purposes of calculation of the
liquidated damages contemplated in this Section and for purposes of calculation
of the liquidated damages contemplated in the Business Management Agreement and
the Physician Employment Agreement between the Physician and the New P.A., the
aggregate consideration received by Physician and the Company pursuant to this
Agreement shall be in those amounts and in such form as set forth in Schedule
18.1. If the Physician violates this non-competition covenant, Vision 21 shall,
in addition to all other rights and remedies available at law or equity, be
entitled to (a) cancel the number of shares of Common Stock held by the
Physician or the Company or, with respect to shares of Common Stock entitled to
be received by the Physician or the Company, terminate its obligation to deliver
such number of shares of Common Stock valued as set forth in Section 6.6(a) of
the Business Management Agreement, and (b) repayment by Physician to Vision 21
of the fair market value as described above, of Vision 21 Common Stock sold by
Physician; but in no event shall Vision 21 be entitled to offset amounts in
excess of the liquidated damages sum pursuant to this Section 18.1. The
Physician and the Company agree to deliver to Vision 21 the certificates
representing any such shares canceled by Vision 21. Payment and satisfaction by
Physician shall be made within sixty (60) days of notification to Physician by
Vision 21 that Physician has violated this non-competition covenant.

                  e.       Notwithstanding anything contained herein, this
Section 18.1 shall not be construed to (i) limit the freedom of any patient of
the Physician or the Company to choose the facility or physician from whom such
patient shall receive health-care services or (ii) limit or interfere with the
Physician's ability to exercise his professional medical judgment in treating
his patients or his ability to provide medical services to his patients.

         18.2.    Physician and Company Confidentiality Covenant. From the date
hereof, the Physician and the Company shall not, directly or indirectly, use for
any purpose, other than in connection with the performance of the Physician's
duties under the Physician Employment Agreement with the New P.A., or disclose
to any third party, any material information of Vision 21, the Company or the
Partnership, as appropriate (whether written or oral), including any business
management or economic studies, patient lists, proprietary forms, proprietary
business or management methods, marketing data, fee schedules, or trade secrets
of Vision 21, of the Company or of the Partnership, as applicable, and including
the terms and provisions of this Agreement and any transaction or document
executed by the parties pursuant to this Agreement. Notwithstanding the
foregoing, the Physician and the Company may disclose information that the
Physician or the Company can establish (a) is or becomes generally available to
and known by the public or medical community (other than as a result of an
unpermitted disclosure directly or indirectly by the Physician or the Company or
their respective Affiliates, advisors, or representatives); (b) is or becomes
available to the Physician or the Company on a nonconfidential basis from a
source other than Vision 21 or its Affiliates, advisors or representatives,
provided that such source is not and was not bound by a confidentiality
agreement with or other obligation of secrecy to Vision 21 or its Affiliates,
advisors or representatives of which the Physician or the Company has knowledge;
or (c) has already been or is hereafter independently acquired or developed by
the Physician or the


                                      -62-
<PAGE>   63

Company without violating any confidentiality agreement with or other obligation
of secrecy to Vision 21, the Company or their respective Affiliates, advisors or
representatives. Without limiting the other possible remedies to Vision 21 for
the breach of this covenant, the Physician and the Company agree that injunctive
or other equitable relief shall be available to enforce this covenant. The
Physician and the Company further agree that if any restriction contained in
this Section 18.2 is held by any court to be unenforceable or unreasonable, a
lesser restriction shall be enforced in its place and the remaining restrictions
contained herein shall be enforced independently of each other.

         18.3.    Survival.  The parties acknowledge and agree that this Article
18 shall survive the Closing of the transactions contemplated herein.

         19.      DISPUTES.

         19.1.    Mediation and Arbitration. Any dispute, controversy or claim
(excluding claims arising out of an alleged breach of Article 18 of this
Agreement) arising out of this Agreement, or the breach thereof, that cannot be
settled through negotiation shall be settled (a) first, by the parties trying in
good faith to settle the dispute by mediation under the Commercial Mediation
Rules of the AAA (such mediation session to be held in Tampa, Florida and to
commence within 15 days of the appointment of the mediator by the AAA), and (b)
if the controversy, claim or dispute cannot be settled by mediation, then by
arbitration administered by the AAA under its Commercial Arbitration Rules (such
arbitration to be held in Tampa, Florida, before a single arbitrator and to
commence within 15 days of the appointment of the arbitrator by the AAA), and
judgment on the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof.

         20.      MISCELLANEOUS

         20.1.    Taxes. Physician and the Company shall pay all transfer taxes,
sales and other taxes and charges, imposed by the State, if any, which may
become payable in connection with the transactions and documents contemplated
hereunder (excluding any of such taxes which may be attributable to services to
be provided by Vision 21 under the Business Management Agreement). Vision 21
shall pay all transfer taxes, sales and other taxes and charges imposed by the
State of Florida, if any, which may become payable in connection with the
transactions and documents contemplated hereunder (excluding any of such taxes
which may be attributable to services to be provided by Vision 21 under the
Business Management Agreement).

         20.2.    Remedies Not Exclusive. No remedy conferred by any of the
specific provisions of this Agreement or any document contemplated by this
Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise. The election of any one or more remedies by any party hereto shall
not constitute a waiver of the right to pursue other available remedies.


                                      -63-

         20.3. Parties Bound. Except to the extent otherwise expressly provided
herein, this Agreement shall be binding upon and inure to the benefit of the

guardians, successors and assigns; and no other person shall have any right,
benefit or obligation hereunder.

         20.4. Notices. All notices, reports, records or other communications

or to such other address as such party may have given to the other parties by
notice pursuant to this Section 20.4. Notice shall be deemed given on the date
of delivery, in the case of personal delivery or telecopy, or on the delivery or
refusal date, as specified on the return receipt, in the case of overnight
courier or registered or certified mail.

         20.5.    Choice of Law. This Agreement shall be construed, interpreted,
and the rights of the parties determined in accordance with, the laws of the
State of Florida except with respect to matters of law concerning the internal
affairs of any corporate or partnership entity which is a party to or the
subject of this Agreement, and as to those matters the law of the state of
incorporation or organization of the respective entity shall govern.

         20.6.    Entire Agreement; Amendments and Waivers. This Agreement,
together with the documents contemplated by this Agreement and all Exhibits and
Schedules hereto and thereto, constitute the entire agreement between the
parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof. No
supplement, modification or waiver of any of the provisions of this Agreement
shall be binding unless it shall be specifically designated to be a supplement,
modification or waiver of this Agreement and shall be executed in writing by the
party to be bound thereby. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provision hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver
unless otherwise expressly provided.

         20.7.    Confidentiality Agreements.  The provisions of any prior
confidentiality agreements and letters of intent between or among Vision 21, the
Company, the Partnership and the Physician, as amended, shall terminate and
cease to be of any force or effect at and upon the Closing.

         20.8.    Modification Clause. It is the intention of the parties hereto
to conform strictly to applicable laws regarding the practice and regulation of
medicine, whether such laws are now or hereafter in effect, including the laws
of the United States of America, the State or any other applicable jurisdiction,
and including any subsequent revisions to, or judicial interpretations of, those
laws, in each case to the extent they are applicable to this Agreement (the
"Applicable Laws"). Accordingly, if the ownership of any Nonmedical Asset by
Vision 21 violates any Applicable Law, then the parties hereto agree as follows:
(a) the provisions of this Section 20.8 shall govern and control; (b) if none of
the parties hereto are materially economically disadvantaged, then any
Nonmedical Asset, the ownership of which violates any Applicable Law, shall be
deemed to have never been owned by Vision 21; (c) if one or more of the parties
hereto is materially economically disadvantaged, then the parties hereto agree
to negotiate in good faith such changes to the structure and terms of the
transactions provided for in this Agreement as may be necessary to make these
transactions, as restructured, lawful under applicable laws and regulations,
without materially disadvantaging either party; (d) this Agreement shall be
deemed modified and amended; and (e) the parties to this Agreement shall execute
and deliver all documents or instruments necessary to effect or evidence the
provisions of this Section 20.8.

subsidiary. In the event of such assignment, Vision 21 shall remain liable
hereunder.

         20.10.   Attorneys' Fees. Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to this
Agreement or the other documents contemplated with respect to the
interpretation, enforcement or breach hereof, the prevailing party in such
action shall be entitled to an award of all reasonable costs of litigation or
arbitration, including, without limitation, attorneys' fees, to be paid by the
losing party, in such amounts as may be determined by the court having
jurisdiction of such action or proceeding, by the arbitrators deciding such
action or proceeding or as agreed to by the parties hereto.

         20.11.   Further Assurances. From time to time hereafter and without
further consideration, each of the parties hereto shall execute and deliver such
additional or further instruments of conveyance, assignment and transfer and
take such other actions as any of the other parties hereto may reasonably
request in order to more effectively consummate the transactions contemplated
hereunder or as shall be reasonably necessary or appropriate in connection with
the carrying out of the parties' respective obligations hereunder for the
purposes of this Agreement.

         20.12.   Announcements and Press Releases. Any press releases or any
other public announcements concerning this Agreement or the transactions
contemplated hereunder shall be approved in advance by Vision 21; provided,
however, that if Physician or the Company reasonably believes that he or it has
a legal obligation to make a press release and the consent Vision 21 cannot be
obtained, then the release may be made without such approval.

         20.13.   No Tax Representations. Each party acknowledges that it is
relying solely on its advisors to determine the tax consequences of the
transactions contemplated hereunder and that no representation or warranty has
been made by any party as to the tax consequences of such transactions except as
otherwise specifically set forth in this Agreement.

         20.14.   No Rights as Stockholder. The Physician shall have no rights
as a stockholder with respect to any shares of Common Stock until the issuance
of a stock certificate evidencing such shares. Except as otherwise provided in
the Agreement, no adjustment shall be made for dividends or distributions or
other rights for which the record date is prior to such date any stock
certificate is issued.

         20.15.   Multiple Counterparts.  This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

         20.16.   Headings.  The headings of the several articles and sections
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning or interpretation of this Agreement.

         20.17.   Severability. Each article, section and subsection of this
Agreement constitutes a separate and distinct undertaking, covenant or provision
of this Agreement. If any such provision shall finally be determined to be
unlawful, such provision shall be deemed severed from this Agreement, but every
other provision of this Agreement shall remain in full force and effect.

         20.18.   Form of Transaction. If after the execution hereof, Vision 21
determines that the sale of the Nonmedical Assets of the Company and the
Partnership can be better achieved through a different form of transaction
without economic injury to the Company or the Physician, or delay of the
consummation of the transaction, the Company and the Physician shall cooperate
(and the Company shall use its best efforts to cause the Partnership to
cooperate) in revising the structure of the transaction and shall negotiate in
good faith to so amend this Agreement; provided, that Vision 21 shall reimburse
the Company, the Partnership and the Physician at Closing for all reasonable
additional expenses incurred by the Company, the Partnership and the Physician
as a result of such change in form.

or (b) paid accounts payable at a reduced or delayed rate during such period,
Vision 21 shall seek an adjustment to the Purchase Price. In the event that the

upon net income created by the change in amortization of such goodwill. Vision
21 shall notify the Shareholder in writing within seventy-five (75) days of the
Closing Date of its decision to seek an adjustment of the Purchase Price, the
amount of the proposed adjustment and its reasons for such decision. If the
Shareholder does not notify Vision 21 within ten (10) days of the Shareholder's
receipt of such notice that the Shareholder objects to the proposed adjustment,
then the proposed adjustment shall take place and shall be final. If the
Shareholder notifies Vision 21 within the above-described ten (10) day period
that the Shareholder objects to the proposed adjustment, then Vision 21 and the
Shareholder shall in good faith negotiate an appropriate amount of the
adjustment, if any, which should be made. During all time periods following
Vision 21's notice that it intends to adjust the Purchase Price until the
adjustment is finalized, Vision 21 shall provide to Shareholder and his
accountants full access to all relevant books, records and work papers utilized
in preparing the proposed Purchase Price adjustment. The adjustment may be
settled in cash or Vision 21 Common Stock at the Shareholder's option.

            2.8. Subsequent Actions. If, at any time after the Closing Date,

desirable to vest, perfect or confirm of record or otherwise in Vision 21 its
right, title or interest in, to or under any of the rights, properties or assets
of the Company acquired or to be acquired by Vision 21 as a result of, or in
connection with, the Transaction, or otherwise to carry out this Agreement, the

True, correct and complete copies of the written Commitments, and true, correct
and complete written descriptions of the oral Commitments, have heretofore been
delivered or made available to Vision 21. Except as set forth on Schedule 3.12
and to the Company's best knowledge, there are no existing or asserted defaults,
events of default or events, occurrences, acts or omissions that, with the
giving of notice or lapse of time or both, would constitute defaults by the
Company or, to the best knowledge of the Company, any other party to a material
Commitment, and no penalties have been incurred nor are amendments pending, with
respect to the material Commitments, except as described on Schedule 3.12. The
Commitments are in full force and effect and are valid and enforceable
obligations of the Company, and to the best knowledge of the Company, are valid
and enforceable obligations of the other parties thereto, in accordance with
their respective terms, and no defenses, off-sets or counterclaims have been
asserted or, to the best knowledge of the Company, may be made by any party
thereto (other than the Company), nor has the Company waived any rights
thereunder, except as described on Schedule 3.12. Except as set forth on
Schedule 3.12, no consents or approvals are required under the terms of any
agreement listed on Schedule 3.12 in connection with the transactions
contemplated herein, including, without limitation, the transfer of any such

                   b. No Cancellation or Termination of Commitment. Except as
disclosed pursuant to this Agreement or contemplated hereby and except where
such default would not have a Material Adverse Effect on the Optical Business,
(i) neither the Company nor the Shareholder has received notice of any plan or
intention of any other party to any Commitment to exercise any right to cancel
or terminate any Commitment, and the Company does not know of any fact that
would justify the exercise of such a right; and (ii) neither the Company nor the
Shareholder currently contemplates, or has reason to believe any other person
currently contemplates, any amendment or change to any Commitment.

             3.13. Insurance. The Company carries property, liability,
malpractice, workers' compensation and such other types of insurance pursuant to
the insurance policies listed and briefly described on Schedule 3.13 (the
"Insurance Policies"). The Insurance Policies are all of the insurance policies
of the Company relating to the business of the Company and the Non-optical
Assets. All of the Insurance Policies are issued by insurers of recognized
responsibility, and, to the best knowledge of the Company, are valid and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies. Except as set forth in Schedule 3.13, no
consent or approval is required for, and no other impediment or restriction
exists that will prohibit or limit, the transfer of any such Insurance Policies
included within the Non-optical Assets in accordance with the terms of this
Agreement. All Insurance Policies shall be maintained in force without
interruption up to and including the Closing Date. True, complete and correct
copies of all Insurance Policies have been provided or made available to Vision
21. Except as set forth on Schedule 3.13, neither the Company nor the
Shareholder has received any notice or other communication from any issuer of
any Insurance Policy cancelling such policy, materially increasing any
deductibles or retained amounts thereunder, and to the actual knowledge of the
Company, no such cancellation or increase of deductibles, retainages or premiums
is threatened. Except as set forth on Schedule 3.13, the Company does not have
any outstanding claims, settlements or premiums owed against any Insurance
Policy, and the Company has given all notices or has presented all potential or
actual claims under any Insurance Policy in due and timely fashion. Schedule
3.13 also sets forth a list of all claims under any Insurance Policy in excess
of $10,000 per occurrence filed by the Company since January 1, 1994.

             3.14. Proprietary Rights and Information. Set forth on Schedule
3.14 is a true and correct description of the following ("Proprietary Rights"):

                   a. all trademarks, trade-names, service marks and other
trade designations, including common law rights, registrations and applications
therefor, and all patents and applications therefor currently owned, in whole or
in part, by the Company, and all licenses, royalties, assignments and other
similar agreements relating to the foregoing to which the Company is a party
(including the expiration date thereof if applicable); and

                   b. all agreements relating to technology, know-how or
processes that the Company is licensed or authorized to use by others (other

                                       20

<PAGE>   21

or processes generally available to other organizations engaged in an Optical
Business), or which it licenses or authorizes others to use.

The Company owns or has the legal right to use the Proprietary Rights, and to
the knowledge of the Company, such ownership or use does not conflict, infringe
or violate the rights of any other person. Except as disclosed on Schedule 3.14,
no consent of any person will be required for the use thereof by Vision 21 upon
consummation of the transactions contemplated hereby and the Proprietary Rights
are freely transferable. No claim has been asserted by any person to the
ownership of or for infringement by the Company of the proprietary right of any
other person, and the Company does not know of any valid basis for any such
claim. To the best knowledge of the Company and the Shareholder, the Company has
the right to use, free and clear of any adverse claims or rights of others, all
trade secrets, customer lists and proprietary information required for the
marketing of all merchandise and services formerly or presently sold or marketed
by it.

             3.15. Taxes.

                   a. Filing of Tax Returns. The Company has duly and timely

all federal, state, local or foreign income, excise, corporate, franchise,
property, sales, use, payroll, withholding, provider, value added and other tax
returns and reports (collectively the "Tax Returns") required to be filed by the
United States or any state or any political subdivision thereof or any foreign
jurisdiction. All such Tax Returns or reports are complete and accurate in all
material respects and properly reflect the taxes of the Company for the periods
covered thereby.

                   b. Payment of Taxes. Except for such items as the Company
may be disputing in good faith by proceedings in compliance with applicable law,
which are described on Schedule 3.15, (i) the Company has paid all taxes,
penalties, assessments and interest that have become due with respect to any Tax
Returns that it has filed and has properly accrued on its books and records for
all of the same that have not yet become due, and (ii) the Company is not
delinquent in the payment of any tax, assessment or governmental charge.

                   c. No Pending Deficiencies, Delinquencies, Assessments or
Audits. Except as set forth on Schedule 3.15, the Company has not received any
notice that any tax deficiency or delinquency has been asserted against the
Company. There is no unpaid assessment, proposal for additional taxes,
deficiency or delinquency in the payment of any of the taxes of the Company that

required to be withheld by the Company and paid to governmental agencies for all
income, social security, unemployment insurance, sales, excise, use, and other
taxes have been collected or withheld and paid to the respective governmental
agencies.

no existing violations by the Company of any federal, state or local law or
regulation that could, individually or in the aggregate, result in a Material
Adverse Effect. The Company possesses all necessary licenses, franchises,

in the aggregate, have a Material Adverse Effect. Except as set forth on
Schedule 3.16, since January 1, 1993, the Company has not received any notice
from any federal, state or other governmental authority or agency having
jurisdiction over its properties or activities, or any insurance or inspection
body, that its operations or any of its properties, facilities, equipment, or
business practices fail to comply with any applicable law, ordinance,
regulation, building or zoning law, or requirement of any public or quasi-public

administrative proceedings or investigations instituted or, to the actual
knowledge of the Company or the Shareholder threatened, which affect or could
affect the Non-optical Assets or the operation, business, condition (financial
or otherwise), or results of operations of the Company which (i) if successful
could, individually or in the aggregate, have a Material Adverse Effect or (ii)
could adversely affect the ability of the Company or the Shareholder to effect
the transactions contemplated

of the Company threatened, investigation or inquiry by any governmental
authority or to any remedial obligations under, any federal, state or local laws

Company and the Shareholder have paid or have properly recorded on the Financial
Statements all actually known and undisputed refunds, discounts or adjustments
which have become due pursuant to such claims, and neither the Company nor the

any applicable laws, regulations and licensing requirements or failed to file
with the proper authorities any necessary statements and reports except where
the failure to so comply or file would not, individually or in the aggregate,

Transaction. Vision 21 possesses all necessary licenses, franchises, permits and
governmental authorizations for the conduct of Vision 21's business as now
conducted and after the Closing, as contemplated in this Agreement, except for
such licenses, franchises, permits or governmental authorizations which, if not
possessed by Vision 21, would not have a material adverse effect on the business
of Vision 21. The transactions contemplated by this Agreement will not result in
a default under or a breach or violation of, or adversely affect the rights and
benefits afforded by any such licenses, franchises, permits or government
authorizations, except for any such default, breach or violation that would not,
individually or in the aggregate, have a material adverse effect on the
Transaction. Since January 1, 1993, Vision 21 has not received any notice from
any federal, state




                                       31

or other governmental authority or agency having jurisdiction over its
properties or activities, or any insurance or inspection body, that its
operations or any of its properties, facilities, equipment, or business
practices fail to comply with any applicable law, ordinance, regulation,
building or zoning law, or requirement of any public or quasi-public authority
or body, except where failure to so comply would not, individually or in the
aggregate, have a material adverse effect on the Transaction.

             5.12. Insolvency Proceedings. Vision 21 is not currently under the
jurisdiction of a Federal or state court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

             5.13. Employment of Company's Employees. Vision 21 does not
currently intend to change the existing composition or employment terms of any
of the non-professional personnel which have employment arrangements with the
Company on the effective date of this Agreement (except as is necessary for
Vision 21 to employ such individuals pursuant to the Business Management
Agreement). Vision 21 reserves the right, however, to change the number,
composition or employment terms of such non-professional personnel in the
future.

         6.  SECURITIES LAW MATTERS.

             6.1.  Investment Representations and Covenants of Shareholder.

                   a. Shareholder understands that the Securities will not be
registered under the Securities Act or any state securities laws on the grounds
that the issuance of the Securities is exempt from registration pursuant to
Section 4(2) of the Securities Act under the Securities Act and applicable state
securities laws, and that the reliance of Vision 21 on such exemptions is
predicated in part on the Shareholder's representations, warranties, covenants
and acknowledgements set forth in this Section.

                   b. Except as disclosed on Schedule 6.1(b) attached hereto,
Shareholder represents and warrants that Shareholder is an "accredited investor"

thereunder, except as contemplated in this Agreement, and that Shareholder will
not distribute any of the Securities in violation of the Securities Act. All
Securities shall bear a restrictive legend in substantially the following form:

<PAGE>   33

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE
         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

         In addition, the Securities shall bear any legend required by the
securities or "Blue Sky" laws of any state where Shareholder resides as well as
any other legend deemed appropriate by Vision 21 or its counsel.

                   d. Shareholder represents and warrants that the address set
forth below Shareholder's name on Schedule 6.1(d) is Shareholder's principal
residence.

                   e. Shareholder (i) acknowledges that the Securities issued to
Shareholder at the Closing must be held indefinitely by Shareholder unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that in
such cases where the Rule is not applicable, compliance with some other
registration exemption will be required, and (iii) is aware that Rule 144 is not
currently available for use by Shareholder for resale of any of the Securities
to be acquired by Shareholder upon consummation of the transactions described in
this Agreement.

                   f. Shareholder represents and warrants to Vision 21 that
Shareholder, either alone or together with the assistance of Shareholder's own
professional advisor, has such knowledge and experience in financial and
business matters such that Shareholder is capable of evaluating the merits and
risks of Shareholder's investment in any of the Securities to be acquired by
Shareholder upon consummation of the transactions described in this Agreement.

                   g. Shareholder confirms that Shareholder has had the
opportunity to ask questions of and receive answers from Vision 21 concerning
the terms and conditions of Shareholder's investment in the Securities, and the
Shareholder has received to Shareholder's satisfaction, such additional
information, in addition to that set forth herein, about Vision 21's operations
and the terms and conditions of the offering as Shareholder has requested.

                   h. In order to ensure compliance with the provisions of
paragraph (c) hereof, Shareholder agrees that after the Closing Shareholder will
not sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the Securities Act) without first
complying with either of the following conditions, the expenses and costs of
satisfaction of which shall be fully borne and paid for by Shareholder:

                   i) Vision 21 shall have received a written legal opinion from
legal counsel, which opinion and counsel shall be satisfactory to Vision 21 in
the exercise


                                       33

<PAGE>   34

of its reasonable judgment, or a copy of a "no-action" or interpretive letter of
the Securities and Exchange Commission specifying the nature and circumstances
of the proposed transfer and indicating that the proposed transfer will not be
in violation of any of the registration provisions of the Securities Act and the
rules and regulations promulgated thereunder; or

                   ii) Vision 21 shall have received an opinion from its own
counsel to the effect that the proposed transfer will not be in violation of any
of the registration provisions of the Securities Act and the rules and
regulations promulgated thereunder.

Shareholder also agrees that the certificates or instruments representing the
Securities to be issued to Shareholder pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this Section
and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 6.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.

                   i. Shareholder understands that there can be no assurance
that a Public Offering by Vision 21 will ever occur or if it does occur that it
will be successful.

                   j. Shareholder agrees that he shall be considered an
"affiliate" of Vision 21 for purposes of Rule 144 and agrees to the restrictions
and limitations imposed by Rule 144 on affiliates. Shareholder further agrees
that he shall be considered an affiliate of Vision 21 for Rule 144 purposes even
if he does not meet the technical definition of "affiliate" under Rule 144.

             6.2.  Current Public Information. At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act, as
such Rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC) regarding the availability of current public
information to the extent required to enable any holder of shares of Common
Stock to sell such shares without registration under the Securities Act pursuant
to Rule 144 (or any similar rule or regulation).

         7.  COVENANTS OF THE COMPANY, THE SHAREHOLDER AND THE PRACTICE. The
Company, the Shareholder, and the Practice, jointly and severally, agree that
between the date hereof and the Closing (with respect to the Company's and the

that would have been or would be required to be set forth or described in the
Schedules in order to not materially breach any representation, warranty or

assessments, penalties, liabilities, costs, damages, reasonable attorneys' fees
and expenses (collectively, "Damages") asserted against or incurred by such
entities and individuals (including, but not limited to, any reduction in
payments to or revenues of the Practice) arising out of or resulting from:

                   a. a breach of any representation, warranty or covenant of

                   b. any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, (i) arising out of or based upon any untrue statement
or alleged untrue statement of a material fact relating to the Shareholder, the
Practice or the Company (including its subsidiaries, if any), and provided to
Vision 21 or its counsel by the Company, the Practice or the Shareholder,
specifically for inclusion in a Registration Statement or any prospectus forming
a part thereof, or any amendment thereof or supplement thereto, (ii) arising out
of or based upon any omission or alleged omission to state therein a material
fact relating to the Shareholder, the Practice or the Company (including its
subsidiaries, if any) required to be stated therein or necessary to make the
statements therein not misleading, and not provided to Vision 21 or its counsel
by the Company, the Practice or the Shareholder, provided, however, that such
indemnity shall not inure to the benefit of Vision 21 to the extent that such
untrue statement (or alleged untrue statement) was made, in, or omission (or
alleged omission) occurred in, any preliminary prospectus, and such information
was not so included by Vision 21 and properly delivered to shareholders of
Vision 21 who acquire Vision 21 Common Stock in any Public Offering;

                   c. any filings, reports or disclosures made pursuant to the
IRS Voluntary Compliance Resolution Program, if applicable; and

             14.2. Indemnification by Vision 21. Subject to the terms and
conditions of this Agreement, Vision 21 hereby agrees to indemnify, defend and
hold the Company, the Practice and the Shareholder harmless from and against all

         Notwithstanding anything in this Section 14.2, Vision 21 shall not be
liable for any Damages resulting from any matter not disclosed to Vision 21 by
any of the third parties acquired by Vision 21 in connection with the Recent
Acquisitions.

             14.3. Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                   a. A party claiming indemnification under this Agreement (an
"Indemnified Party") shall promptly (and, in any event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party from whom indemnification is sought (the "Indemnifying
Party") of any third-party claim or claims asserted against the Indemnified
Party ("Third Party Claim") that could give rise to a right of indemnification
under this Agreement and (ii) transmit to the Indemnifying Party a written
notice ("Claim Notice") describing in reasonable detail the nature of the Third
Party Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. Except as set forth in Section 14.6, the failure to promptly deliver
a Claim Notice shall not relieve the Indemnifying Party of its obligations to
the Indemnified Party with respect to the related Third Party Claim except to
the extent that the resulting delay is materially prejudicial to the defense of
such claim. Within thirty (30) days after receipt of any Claim Notice (the
"Election Period"), the Indemnifying Party shall notify the Indemnified Party
(i) whether the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article 14 with respect to such Third Party Claim
and (ii) whether the Indemnifying Party desires, at the sole cost and expense of
the Indemnifying Party, to defend the Indemnified Party against such Third Party
Claim.

                   b. If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). The Indemnifying
Party shall have full control of such defense and proceedings, including any
compromise or settlement thereof. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is entitled to indemnification hereunder), to file, during the Election
Period, any motion, answer or other pleadings that the Indemnified Party shall
deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being
understood and agreed that if an Indemnified Party takes any such action that is
prejudicial and causes a final adjudication that is adverse to the Indemnifying
Party, the Indemnifying Party shall be relieved of its obligations hereunder
with respect to such Third Party Claim). If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim


                                       47

<PAGE>   48

against the person asserting the Third Party Claim or any cross-complaint
against any person. The Indemnified Party may participate in, but not control,
any defense or settlement of any Third Party Claim controlled by the
Indemnifying Party pursuant to Section 14.3(b) and shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnified Party has
been advised by counsel that there may be one or more legal defenses available
to it that are different from or additional to those available to the
Indemnifying Party, then the Indemnified Party may employ separate counsel at
the expense of the Indemnifying Party, and upon written notification thereof,
the Indemnifying Party shall not have the right to assume the defense of such
action on behalf of the Indemnified Party; provided further that the
Indemnifying Party shall not, in connection with any one such action or separate
but substantially similar or related actions in the same jurisdiction arising
out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for the Indemnified Party, which firm shall be designated in writing by the
Indemnified Party.

                   c. If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 14 and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnifying Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

<PAGE>   49

                   d. In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 17.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                   e. Payments of all amounts owing by an Indemnifying Party
pursuant to this Article 14 relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim or (iii) the expiration of the period for appeal of a
final adjudication of the Indemnifying Party's liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by an Indemnifying
Party pursuant to Section 14.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the sixty (60) day Indemnity Notice period or
(ii) the expiration of the period for appeal, if any, of a final adjudication or
arbitration of the Indemnifying Party's liability to the Indemnified Party under
this Agreement.

             14.4. Remedies Not Exclusive. The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity. This Article 14
regarding indemnification shall survive Closing.

             14.5. Costs, Expenses and Legal Fees. Each party hereto agrees to
pay the costs and expenses (including attorneys' fees and expenses) incurred by
the other parties in successfully (a) enforcing any of the terms of this
Agreement, or (b) proving that another party breached any of the terms of this
Agreement.

             14.6. Indemnification Limitations. Notwithstanding the provisions
of Sections 14.1 and 14.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2., 3.3, 3.11, 3.14,
4.3, 5.1, 5.2, 5.3, 5.4, 5.8 and 6.1 may be made at any time, and a claim for
indemnification for a breach of the representations and warranties contained in
Sections 3.9, 3.15, 3.17, 3.18, 3.24, 3.25, 3.26, 3.27, 4.1, 4.4, 4.5, 4.6, 4.7
and 5.7 may be made at any time within the applicable statute of limitations;
(b) indemnification based upon Sections 14.1(b) through (d) and 14.2(b) through
(c) may be made at any time within the applicable statute of limitations; and
(c) the Shareholder shall not be required to indemnify Vision 21 pursuant to
Section 14.1 unless, and to the extent that,


                                       49

<PAGE>   50

the aggregate amount of Damages incurred by Vision 21 shall exceed an amount
equal to two percent (2%) of the total Purchase Price; and (c) the Shareholder
shall not be required to indemnify Vision 21 with respect to a breach of a
representation, warranty or covenant for Damages in excess of the aggregate
Purchase Price received by the Shareholder (other than pursuant to a requirement
to indemnify Vision 21 under Sections 3.26 or 3.27, or unless the breach
involves an intentional breach or fraud by the Shareholder which shall be
unlimited).

             14.7. Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds and such correlative insurance
benefit shall be net of the insurance premium, if any, that becomes due as a
result of such claim.

             14.8. Payment of Indemnification Obligation. In the event that the
Shareholder has an indemnification obligation to Vision 21 hereunder, subject to
Vision 21's approval as set forth below, the Shareholder may satisfy such
obligation by transferring to Vision 21 such number of shares of Vision 21
Common Stock owned by the Shareholder having an aggregate fair market value
(which is the fair market value at such time based on the last reported sale
price of Vision 21 Common Stock on a principal national securities exchange or
other exchange on which the Vision 21 Common Stock is then listed or the last
quoted ask price on any over-the-counter market through which the Vision 21
Common Stock is then quoted on the last trading day immediately preceding the
day on which the Shareholder transfers shares of Vision 21 Common Stock to
Vision 21 hereunder) equal to the indemnification obligation, provided that each
of the following conditions are satisfied:

                   a. The Shareholder shall transfer to Vision 21 good, valid
and marketable title to the shares of Vision 21 Common Stock, free and clear of
all adverse claims, security interests, liens, claims, proxies, options,
stockholders' agreements and encumbrances;

                   b. The Shareholder shall make such representation and
warranties as to title to the stock, absences of security interests, liens,
claims, proxies, stockholders' agreements and other encumbrances and other
matters as reasonably requested by Vision 21; and

                   c. The other terms and conditions of any transaction
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21.

         15. TERMINATION.

             15.1. Termination. This Agreement may be terminated and the
Transaction may be abandoned:

                   a. at any time prior to the Closing Date by mutual agreement
of all parties;

                   b. at any time prior to the Closing Date by Vision 21 if any
representation or warranty of the Company, the Practice or the Shareholder
contained in this Agreement or in any certificate or other document executed and
delivered by the Company, the Practice or the Shareholder pursuant to this
Agreement is or becomes untrue or breached in any material respect or if the
Company, the Practice or the Shareholder fails to comply in any material respect
with any covenant or agreement contained herein, and any such misrepresentation,
noncompliance or breach is not cured, waived or eliminated within twenty (20)
days after receipt of written notice thereof;

                   c. at any time prior to the Closing Date by the Company or
the Practice if any representation or warranty of Vision 21 contained in this
Agreement is or becomes untrue in any material respect or if Vision 21 fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt or written notice thereof;

                   d. at any time prior to the Closing Date by the Company or
the Practice in the event of the failure of any of the conditions precedent set
forth in Article 11 of this Agreement;

                   e. at any time prior to the Closing Date by Vision 21 in the
event of the failure of any of the conditions precedent set forth in Article 10
of this Agreement;

                   f. by Vision 21 if at any time prior to the Closing Date,

21 exercises its right to terminate this Agreement under this subsection, Vision
21 shall reimburse the Company, the Practice and the Shareholder for all
reasonable attorneys' and accountants' fees incurred by the Company, the
Practice and the Shareholder in connection with this Agreement; provided that
Vision 21 shall only reimburse the Company, the Practice and the Shareholder up
to an aggregate maximum amount of One Hundred Thousand and No/100 Dollars
($100,000.00) for such fees; or

                   g. by Vision 21 or the Company if the Transaction shall not
have been consummated by November 30, 1997.

<PAGE>   52

             15.2. Effect of Termination. In the event this Agreement is
terminated pursuant to Section 15.1, Vision 21, the Practice, the Company and
the Shareholder, shall each be entitled to pursue, exercise and enforce any and
all remedies, rights, powers and privileges available at law or in equity,
subject to the limitations set forth in Section 15.1. In the event of a
termination of this Agreement under the provisions of this Article 15, a party
not then in material breach of this Agreement shall stand fully released and
discharged of any and all obligations under this Agreement.

         16. NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

             16.1. Shareholder, the Practice and Company Non-Competition
Covenant.

                   a. The Shareholder, the Practice and the Company recognize
that the covenants of the Shareholder, the Practice and the Company contained in
this Section 16.1 are an essential part of this Agreement and that, but for the
agreement of the Shareholder, the Practice and the Company to comply with such
covenants, Vision 21 would not have entered into this Agreement. The
Shareholder, the Practice and the Company acknowledge and agree that the
Shareholder's, the Practice's and the Company's covenants not to compete are
necessary to ensure the continuation of Vision 21's Optical Business and are
necessary to protect the reputation of Vision 21, and that irreparable and
irrevocable harm and damage will be done to Vision 21 if the Shareholder, the
Practice or the Company compete with the Optical Business or Vision 21. The
Shareholder, the Practice and the Company accordingly agree that for the periods
set forth in the Business Management Agreement the Shareholder, the Practice and
the Company shall not:

                      i)   directly or indirectly, either as principal, agent,
independent contractor, consultant, director, officer, employee, employer,
advisor, stockholder, partner or in any other individual or representative
capacity whatsoever, either for the Shareholder's, the Practice's or the
Company's own benefit or for the benefit of any other person or entity knowingly
(A) hire, attempt to hire, contact or solicit with respect to hiring any
employee of Vision 21 (or of any of its direct or indirect subsidiaries) or (B)
induce or otherwise counsel, advise or encourage any employee of Vision 21 (or
of any of its direct or indirect subsidiaries) to leave the employment of Vision
21;

                      ii)  act or serve, directly or indirectly, as a principal,
agent, independent contractor, consultant, director, officer, employee, employer
or advisor or in any other position or capacity with or for, or acquire a direct
or indirect ownership interest in or otherwise conduct (whether as stockholder,
partner, investor, joint venturer, or as owner of any other type of interest),
any Competing Optical Business as such term is defined herein; provided,
however, that this clause (ii) shall not prohibit the Shareholder, the Practice
or the Company from being the owner of up to 1% of any class of outstanding
securities of any company or entity if such class of securities is publicly
traded; or

                      iii) directly or indirectly, either as principal, agent,
independent, contractor, consultant, director, officer, employee, employer,
advisor, stockholder,


                                       52

<PAGE>   53

partner or in any other individual or representative capacity whatsoever, either
for the Shareholder's, the Practice's or the Company's own benefit or for the
benefit of any other person or entity, call upon or solicit any customers or
clients of the Optical Business.

                   b. For the purposes of this Section 16.1, the term "Competing
Optical Business" shall mean an individual, business, corporation, association,
firm, undertaking, company, partnership, joint venture, organization or other
entity that either (A) conducts a business substantially similar to the Optical
Business within the State, or (B) provides or sells a service which is the same
or substantially similar to, or otherwise competitive with the services provided
by Vision 21's Optical Business within the State; provided, however, that
"Competing Optical Business" shall not include Vision 21, or the Shareholder's
conduct of an Optical Business within the Practice.

                   c. Should any portion of this Section 16.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Shareholder, the Practice or the Company hereunder, and only
in such event, then the Shareholder, the Practice the Company and Vision 21
consent and agree to such limitation on scope, duration or territory as may be
finally adjudicated as enforceable by a court of competent jurisdiction after
the exhaustion of all appeals.

                   d. This covenant shall be construed as an agreement ancillary
to the other provisions of this Agreement, and the existence of any claim or
cause of action of the Shareholder, the Practice or the Company against Vision
21, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Vision 21 of this covenant; provided, however,
that the Shareholder, the Practice and the Company shall not be bound by this
covenant and shall not be obligated to pay the liquidated damages contemplated
in this Section 16.1 if at the time of a breach of this covenant the Business
Management Agreement has already been terminated pursuant to Section 6.2(a) or
6.2(d) thereof. Without limiting other possible remedies to Vision 21 for breach
of this covenant, the Shareholder, the Practice and the Company agree that
injunctive or other equitable relief will be available to enforce the covenants
of this provision. The Shareholder, the Practice, the Company and Vision 21
further expressly acknowledge that the damages that would result from a
violation of this non-competition covenant would be impossible to predict with
any degree of certainty, and agree that liquidated damages in the amount of the
aggregate consideration received by the Company pursuant to this Agreement is
reasonable in light of the severe harm to the Optical Business and Vision 21
which would result in the event that a violation of this non-competition
covenant were to occur. If the Shareholder or the Company violates this
non-competition covenant, Vision 21 shall, in addition to all other rights and
remedies available at law or equity, be entitled to (a) cancel the number of
shares of Common Stock held by the Shareholder or the Company or, with respect
to shares of Common Stock entitled to be received by the Shareholder or the
Company, terminate its obligation to deliver such number of shares of Common
Stock, and (b) repayment by Shareholder to Vision 21 of the fair market value as
described above, of Vision 21 Common Stock sold by Shareholder; but in no event
shall Vision 21 be entitled to offset amounts in excess of the liquidated
damages sum pursuant to this Section 16.1. The


                                       53

<PAGE>   54

Shareholder and the Company agree to deliver to Vision 21 the certificates
representing any such shares canceled by Vision 21. Payment and satisfaction by
Shareholder shall be made within sixty (60) days of notification to Shareholder
by Vision 21 that Shareholder has violated this non-competition covenant.

             16.2. Shareholder, the Practice and Company Confidentiality
Covenant. From the date hereof, the Shareholder, the Practice and the Company
shall not, directly or indirectly, use for any purpose, other than in connection
with the performance of the Shareholder's duties under the Shareholder's
employment agreement with the Practice, if any, or disclose to any third party,
any material information of Vision 21, the Practice or the Company, as
appropriate (whether written or oral), including any business management or
economic studies, patient lists, proprietary forms, proprietary business or
management methods, marketing data, fee schedules, or trade secrets of Vision 21
or of the Company, as applicable, and including the terms and provisions of this
Agreement and any transaction or document executed by the parties pursuant to
this Agreement. Notwithstanding the foregoing, the Shareholder, the Practice and
the Company may disclose information that the Shareholder, the Practice or the
Company can establish (a) is or becomes generally available to and known by the
public or optical community (other than as a result of an unpermitted disclosure
directly or indirectly by the Shareholder, the Practice or the Company or their
respective Affiliates, advisors, or representatives); (b) is or becomes
available to the Shareholder, the Practice or the Company on a nonconfidential
basis from a source other than Vision 21 or its Affiliates, advisors or
representatives, provided that such source is not and was not bound by a
confidentiality agreement with or other obligation of secrecy to Vision 21 or
its Affiliates, advisors or representatives of which the Shareholder, the
Practice or the Company has knowledge; or (c) has already been or is hereafter
independently acquired or developed by the Shareholder, the Practice or the
Company without violating any confidentiality agreement with or other obligation
of secrecy to Vision 21, the Company or their respective Affiliates, advisors or
representatives. Without limiting the other possible remedies to Vision 21 for
the breach of this covenant, the Shareholder, the Practice and the Company agree
that injunctive or other equitable relief shall be available to enforce this
covenant. The Shareholder, the Practice and the Company further agree that if
any restriction contained in this Section 16.2 is held by any court to be
unenforceable or unreasonable, a lesser restriction shall be enforced in its
place and the remaining restrictions contained herein shall be enforced

interpreted, and the rights of the parties determined in accordance with, the

of incorporation or organization of the respective entity shall govern.

             18.6. Entire Agreement; Amendments and Waivers. This Agreement,
together with the documents contemplated by this Agreement and all Exhibits and
Schedules hereto and thereto, constitute the entire agreement between the
parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof. No
supplement, modification or waiver of any of the provisions of this Agreement
shall be binding unless it shall be specifically designated to be a supplement,
modification or waiver of this Agreement and shall


                                       56

<PAGE>   57

be executed in writing by the party to be bound thereby. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided.

             18.7. Confidentiality Agreements. The provisions of any prior
confidentiality agreements and letters of intent between or among Vision 21, the
Company and the Shareholder, as amended, shall terminate and cease to be of any
force or effect at and upon the Closing.

             18.8. Modification Clause. It is the intention of the parties
hereto to conform strictly to applicable laws regarding the practice and
regulation of medicine and regulation of the Optical Business, whether such laws
are now or hereafter in effect, including the laws of the United States of
America, the State or any other applicable jurisdiction, and including any
subsequent revisions to, or judicial interpretations of, those laws, in each
case to the extent they are applicable to this Agreement (the "Applicable
Laws"). Accordingly, if the ownership of any Non-optical Asset by Vision 21
violates any Applicable Law, then the parties hereto agree as follows: (a) the
provisions of this Section 18.8 shall govern and control; (b) if none of the
parties hereto are materially economically disadvantaged, then any Non-optical
Asset, the ownership of which violates any Applicable Law, shall be deemed to
have never been owned by Vision 21; (c) if one or more of the parties hereto is
materially economically disadvantaged, then the parties hereto agree to
negotiate in good faith such changes to the structure and terms of the
transactions provided for in this Agreement as may be necessary to make these
transactions, as restructured, lawful under applicable laws and regulations,
without materially disadvantaging either party; (d) this Agreement shall be
deemed modified and amended; and (e) the parties to this Agreement shall execute
and deliver all documents or instruments necessary to effect or evidence the
provisions of this Section 18.8.

             18.9. Assignment. The Agreement may not be assigned by operation of
law or otherwise except that Vision 21 shall have the right to assign this
Agreement, at any time, to any Affiliate or direct or indirect wholly-owned
subsidiary. In the event of such assignment, Vision 21 shall remain liable
hereunder.

             18.10. Attorneys' Fees. Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to this
Agreement or the other documents contemplated with respect to the
interpretation, enforcement or breach hereof, the prevailing party in such
action shall be entitled to an award of all reasonable costs of litigation or
arbitration, including, without limitation, attorneys' fees, to be paid by the
losing party, in such amounts as may be determined by the court having
jurisdiction of such action or proceeding, by the arbitrators deciding such
action or proceeding, or as agreed to by the parties hereto.

             18.11. Further Assurances. From time to time hereafter and without
further consideration, each of the parties hereto shall execute and deliver such
additional or further instruments of conveyance, assignment and transfer and
take such other actions as any of the other parties hereto may reasonably
request in order to more effectively consummate the


                                       57

<PAGE>   58

transactions contemplated hereunder or as shall be reasonably necessary or
appropriate in connection with the carrying out of the parties' respective
obligations hereunder for the purposes of this Agreement.

             18.12. Announcements and Press Releases. Any press releases or any
other public announcements concerning this Agreement or the transactions
contemplated hereunder shall be approved in advance by Vision 21; provided,
however, that if Shareholder or the Company reasonably believes that he or it
has a legal obligation to make a press release and the consent of Vision 21
cannot be obtained, then the release may be made without such approval.

             18.13. No Tax Representations. Each party acknowledges that it is
relying solely on its advisors to determine the tax consequences of the
transactions contemplated hereunder and that no representation or warranty has
been made by any party as to the tax consequences of such transactions except as
otherwise specifically set forth in this Agreement.

             18.14. No Rights as Stockholder. The Company and the Shareholder
shall have no rights as a stockholder with respect to any shares of Common Stock
until the issuance of a stock certificate evidencing such shares. Except as
otherwise provided in the Agreement, no adjustment shall be made for dividends
or distributions or other rights for which the record date is prior to such date
any stock certificate is issued.

             18.15. Multiple Counterparts. This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

             18.16. Headings. The headings of the several articles and sections
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning or interpretation of this Agreement.

             18.17. Severability. Each article, section and subsection of this
Agreement constitutes a separate and distinct undertaking, covenant or provision
of this Agreement. If any such provision shall finally be determined to be
unlawful, such provision shall be deemed severed from this Agreement, but every
other provision of this Agreement shall remain in full force and effect.

             18.18. Form of Transaction. If after the execution hereof, Vision
21 determines that the sale of the Non-optical Assets of the Company can be
better achieved through a different form of transaction without economic injury
to the Company, the Practice or the Shareholder, or delay of the consummation of
the transaction, the Company, the Practice and the Shareholder shall cooperate
in revising the structure of the transaction and shall negotiate in good faith
to so amend this Agreement; provided, that Vision 21 shall reimburse the
Company, New P.c. and the Shareholder at Closing for all reasonable additional
expenses incurred by the Company, the Practice and the Shareholder as a result
of such change in form.

amount of the proposed adjustment and its reasons for such decision. If the

then the proposed adjustment shall take place and shall be final. If the
Shareholder notifies Vision 21 within the above-described ten (10) day period

Shareholder shall in good faith negotiate an appropriate amount of the
adjustment, if any, which should be made. During all time periods following

adjustment is finalized, Vision 21 shall provide to Shareholder and his

any other way to provide funds in respect of or to guarantee or assume in any

           5.11. Compliance with Laws. Vision 21 and the Subsidiary have not
failed to comply with any applicable laws, regulations and licensing
requirements or failed to file with the proper authorities any necessary
statements and reports except where the failure to so comply or file would not,
individually or in the aggregate, have a material adverse effect on the
Transaction. There are no existing violations by Vision 21 or the Subsidiary of
any federal, state or local law or regulation that could, individually or in the
aggregate, have a material adverse effect on the Transaction. Vision 21 and the
Subsidiary possess all necessary licenses, franchises, permits and governmental
authorizations for the conduct of Vision 21's and the Subsidiary's respective
businesses as now conducted and after the Closing, as contemplated in this
Agreement, except for such licenses, franchises, permits or governmental
authorizations which, if not possessed by Vision 21 or the Subsidiary, would not
have a material adverse effect on the business of Vision 21 or the Subsidiary.
The transactions contemplated by this Agreement will not result in a default
under or a breach or violation of, or adversely affect the rights and benefits
afforded by any such licenses, franchises, permits or government authorizations,
except for any such default, breach or violation that would not, individually or
in the aggregate, have a material adverse effect on the Transaction. Since
January 1, 1993, neither Vision 21 nor the Subsidiary has received any notice
from any federal, state or other governmental authority or agency having
jurisdiction over their respective properties or activities, or any insurance or
inspection body, that their respective operations or any of their respective
properties, facilities, equipment, or business practices fail to comply with any
applicable law, ordinance, regulation, building or zoning law, or requirement of
any public or quasi-public authority or body, except where failure to so comply
would not, individually or in the aggregate, have a material adverse effect on
the Transaction.

           5.12. Insolvency Proceedings. Neither Vision 21 nor the Subsidiary is
currently under the jurisdiction of a Federal or state court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

           5.13. Employment of Company's Employees. Neither Vision 21 nor the
Subsidiary currently intends to change the existing composition or employment
terms of any of the non-professional personnel which have employment
arrangements with the Company on the effective date of this Agreement (except as
is necessary for Vision 21 to employ such individuals pursuant to the Business
Management Agreement). Vision 21 and the Subsidiary reserve the right, however,
to change the number, composition or employment terms of such non-professional
personnel in the future.

       6.  SECURITIES LAW MATTERS.

           6.1. Investment Representations and Covenants of Shareholder.

                a. Shareholder understands that the Securities will not be
registered under the Securities Act or any state securities laws on the grounds
that the issuance of the Securities is exempt from registration pursuant to
Section 4(2) of the Securities Act under the Securities Act and applicable state
securities laws, and that the reliance of Vision 21 on such exemptions is
predicated in part on the Shareholder's representations, warranties, covenants
and acknowledgements set forth in this Section.

                b. Except as disclosed on Schedule 6.1(b) attached hereto,
Shareholder represents and warrants that Shareholder is an "accredited investor"
or "sophisticated investor" as defined under the Securities Act and state "Blue
Sky" laws, or that Shareholder has utilized, to the extent necessary to be
deemed a sophisticated investor under the Securities Act and State "Blue Sky"
laws, the assistance of a professional advisor.

                c. Shareholder represents and warrants that the Securities to be
acquired by Shareholder upon consummation of the transactions described in this
Agreement will be acquired by Shareholder for Shareholder's own account, not as
a nominee or agent, and without a view to resale or other distribution within
the meaning of the Securities Act and the rules and regulations thereunder,
except as contemplated in this Agreement, and that Shareholder will not
distribute any of the Securities in violation of the Securities Act. All
Securities shall bear a restrictive legend in substantially the following form:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE
         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

         In addition, the Securities shall bear any legend required by the
securities or "Blue Sky" laws of any state where Shareholder resides as well as
any other legend deemed appropriate by Vision 21 or its counsel.

                d. Shareholder represents and warrants that the address set
forth below Shareholder's name on Schedule 6.1(d) is Shareholder's principal
residence.

                e. Shareholder (i) acknowledges that the Securities issued to
Shareholder at the Closing must be held indefinitely by Shareholder unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that in
such cases where the Rule is not applicable, compliance with some other
registration


                                       32

<PAGE>   33



exemption will be required, and (iii) is aware that Rule 144 is not currently
available for use by Shareholder for resale of any of the Securities to be
acquired by Shareholder upon consummation of the transactions described in this
Agreement.

                f. Shareholder represents and warrants to Vision 21 that
Shareholder, either alone or together with the assistance of Shareholder's own
professional advisor, has such knowledge and experience in financial and
business matters such that Shareholder is capable of evaluating the merits and
risks of Shareholder's investment in any of the Securities to be acquired by
Shareholder upon consummation of the transactions described in this Agreement.

                g. Shareholder confirms that Shareholder has had the opportunity
to ask questions of and receive answers from Vision 21 concerning the terms and
conditions of Shareholder's investment in the Securities, and the Shareholder
has received to Shareholder's satisfaction, such additional information, in
addition to that set forth herein, about Vision 21's operations and the terms
and conditions of the offering as Shareholder has requested.

                h. In order to ensure compliance with the provisions of
paragraph (c) hereof, Shareholder agrees that after the Closing Shareholder will
not sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the Securities Act) without first
complying with either of the following conditions, the expenses and costs of
satisfaction of which shall be fully borne and paid for by Shareholder:

                    i)  Vision 21 shall have received a written legal opinion
from legal counsel, which opinion and counsel shall be satisfactory to Vision 21
in the exercise of its reasonable judgment, or a copy of a "no-action" or
interpretive letter of the Securities and Exchange Commission specifying the
nature and circumstances of the proposed transfer and indicating that the
proposed transfer will not be in violation of any of the registration provisions
of the Securities Act and the rules and regulations promulgated thereunder; or

                    ii) Vision 21 shall have received an opinion from its own
counsel to the effect that the proposed transfer will not be in violation of any
of the registration provisions of the Securities Act and the rules and
regulations promulgated thereunder.

Shareholder also agrees that the certificates or instruments representing the
Securities to be issued to Shareholder pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this Section
and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 6.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.


                                       33

<PAGE>   34



                 i. Shareholder understands that there can be no assurance that
a Public Offering by Vision 21 will ever occur or if it does occur that it will
be successful.

                 j. Shareholder agrees that he shall be considered an
"affiliate" of Vision 21 for purposes of Rule 144 and agrees to the restrictions
and limitations imposed by Rule 144 on affiliates. Shareholder further agrees
that he shall be considered an affiliate of Vision 21 for Rule 144 purposes even
if he does not meet the technical definition of "affiliate" under Rule 144.

            6.2. Current Public Information. At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act, as

described in Section 12.1(f);

                   f.  the executed Lease Assignments;

                   g.  the Purchase Price; and

appropriate, as the Company, the Shareholder or their counsel shall reasonable
request, to carry out and effect the purpose and intent of this Agreement.

                 12.3. Release of Escrow Materials. Shumaker, Loop & Kendrick,
LLP (the "Escrow Agent") shall release the agreements, certificates,
instruments, documents and other materials described in Sections 12.1 and 12.2

Subsidiary, the Shareholder and the Company shall have sent written notice to
the Escrow Agent stating that the conditions to release of the escrowed

Subsidiary, the Shareholder and the Company have not notified the Escrow Agent
in writing that they are satisfied with or have waived all of the conditions to
the release of the escrowed documents, the Escrow Agent shall immediately return
any consideration by Vision 21 held by it to Vision 21 and shall promptly
destroy or return the foregoing materials to the parties sending such materials.

         13.     POST CLOSING MATTERS.

                 13.1. Further Instruments of Transfer. From and after the

carry out the purpose and intent of this Agreement.

             13.2. Access to Books and Records. From and after the Closing
Date, at the request of any party hereto, each of the other parties shall
reasonably cooperate in providing the requesting party with access to such other
parties' personnel who are knowledgeable concerning, and books and records which
are relevant to, the inquiry by the requesting party; provided, however, that
(a) such personnel shall be available at, and the access to such books and
records shall be granted at the responding party's business premises and during
the responding party's regular business hours, and (b) the inquiry shall be for
a legitimate business purpose, including tax filings and compliance, defending
against litigation or other claims, or for any other legitimate business
purpose. All copies of such books and records shall be at the requesting party's
expense. Each of the parties to this Agreement shall retain all books and
records with respect to the transactions contemplated herein for a minimum of
five (5) years from the Closing Date.

         14. REMEDIES.

             14.1. Indemnification by the Company and Shareholder. Subject to
the terms and conditions of this Agreement, the Company and the Shareholder,
jointly and severally, agree to indemnify, defend and hold Vision 21, the
Subsidiary and their respective directors, officers, employees, agents,
attorneys and affiliates harmless from and against all losses, claims,
obligations, demands, assessments, penalties, liabilities, costs, damages,
reasonable attorneys' fees and expenses (collectively, "Damages") asserted
against or incurred by such entities and individuals (including, but not limited
to, any reduction in payments to or revenues of Sever, Pusateri & Cortelli,
M.D., P.A.) arising out of or resulting from:

                   a. a breach of any representation, warranty or covenant of
the Company or the Shareholder contained herein or in any schedule or
certificate delivered hereunder;

                   b. any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, (i) arising out of or based upon any untrue statement
or alleged untrue statement of a material fact relating to the Shareholder or
the Company (including its subsidiaries, if any), and provided to Vision 21 or
its counsel by the Company or the Shareholder, specifically for inclusion in a
Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, (ii) arising out of or based upon any
omission or alleged omission to state therein a material fact relating to the
Shareholder or the Company (including its subsidiaries, if any) required to be
stated therein or necessary to make the statements therein not misleading, and
not provided to Vision 21 or its counsel by the Company or the Shareholder,
provided, however, that such indemnity shall not inure to the benefit of Vision
21 to the extent that such untrue statement (or alleged untrue statement) was
made, in, or omission (or alleged omission) occurred in, any preliminary
prospectus, and such information was not so included by Vision 21 and properly
delivered to shareholders of Vision 21 who acquire Vision 21 Common Stock in any
Public Offering;


                                       45

<PAGE>   46



                   c. any filings, reports or disclosures made pursuant to the
IRS Voluntary Compliance Resolution Program, if applicable; and

                   d. any liability arising from any alleged unlawful sale or
offer to sell or transfer any of the Common Stock by Shareholder.

             14.2. Indemnification by Vision 21 and the Subsidiary. Subject to
the terms and conditions of this Agreement, Vision 21 and the Subsidiary,
jointly and severally, hereby agree to indemnify, defend and hold the Company
and the Shareholder harmless from and against all damages asserted against or
incurred by it or him arising out of or resulting from:

                   a. a breach by Vision 21 or the Subsidiary of any
representation, warranty or covenant of Vision 21 or the Subsidiary contained
therein or in any schedule or certificate delivered hereunder;

                   b. any liability under the Securities Act, the Exchange Act
or any other federal or state "Blue Sky" or securities law or regulation, at
common law or otherwise, arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to Vision 21 or the
Subsidiary, contained in any preliminary prospectus, Registration Statement or
any prospectus forming a part thereof, or any amendment thereof or supplement
thereto, arising out of or based upon any omission or alleged omission to state
therein a material fact relating to Vision 21 (including the Subsidiary and
Vision 21's other subsidiaries), required to be stated therein or necessary to
make the statements therein not misleading; and

                   c. any filings, reports or disclosures made pursuant to the
IRS Voluntary Compliance Resolution Program, if applicable.

         Notwithstanding anything in this Section 14.2, neither Vision 21 nor
the Subsidiary shall be liable for any Damages resulting from any matter not
disclosed to Vision 21 by any of the third parties acquired by Vision 21 in
connection with the Recent Acquisitions.

            14.3.  Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                   a. A party claiming indemnification under this Agreement (an
"Indemnified Party") shall promptly (and, in any event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party from whom indemnification is sought (the "Indemnifying
Party") of any third-party claim or claims asserted against the Indemnified
Party ("Third Party Claim") that could give rise to a right of indemnification
under this Agreement and (ii) transmit to the Indemnifying Party a written
notice ("Claim Notice") describing in reasonable detail the nature of the Third
Party Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for indemnification under this
Agreement. Except as set forth in Section 14.6, the failure to


                                       46

<PAGE>   47



promptly deliver a Claim Notice shall not relieve the Indemnifying Party of its
obligations to the Indemnified Party with respect to the related Third Party
Claim except to the extent that the resulting delay is materially prejudicial to
the defense of such claim. Within thirty (30) days after receipt of any Claim
Notice (the "Election Period"), the Indemnifying Party shall notify the
Indemnified Party (i) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article 14 with respect to such
Third Party Claim and (ii) whether the Indemnifying Party desires, at the sole
cost and expense of the Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

                  b. If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 14.3(b). The Indemnifying
Party shall have full control of such defense and proceedings, including any
compromise or settlement thereof. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is entitled to indemnification hereunder), to file, during the Election
Period, any motion, answer or other pleadings that the Indemnified Party shall
deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being
understood and agreed that if an Indemnified Party takes any such action that is
prejudicial and causes a final adjudication that is adverse to the Indemnifying
Party, the Indemnifying Party shall be relieved of its obligations hereunder
with respect to such Third Party Claim). If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to
Section 14.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.


                                       47

<PAGE>   48



                  c. If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 14.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 14.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 14 and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnifying Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control any defense or settlement controlled by the
Indemnified Party pursuant to this Section 14.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

                  d. In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 17.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  e. Payments of all amounts owing by an Indemnifying Party
pursuant to this Article 14 relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim or (iii) the expiration of the period for appeal


                                       48

<PAGE>   49



of a final adjudication of the Indemnifying Party's liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by an Indemnifying
Party pursuant to Section 14.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the sixty (60) day Indemnity Notice period or
(ii) the expiration of the period for appeal, if any, of a final adjudication or
arbitration of the Indemnifying Party's liability to the Indemnified Party under
this Agreement.

             14.4. Remedies Not Exclusive. The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity. This Article 14
regarding indemnification shall survive Closing.

             14.5. Costs, Expenses and Legal Fees. Each party hereto agrees to
pay the costs and expenses (including attorneys' fees and expenses) incurred by
the other parties in successfully (a) enforcing any of the terms of this
Agreement, or (b) proving that another party breached any of the terms of this
Agreement.

             14.6. Indemnification Limitations. Notwithstanding the provisions
of Sections 14.1 and 14.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2., 3.3, 3.11, 3.14,
4.3, 5.1, 5.2, 5.3, 5.4, 5.8 and 6.1 may be made at any time, and a claim for
indemnification for a breach of the representations and warranties contained in
Sections 3.9, 3.15, 3.17, 3.18, 3.24, 3.25, 3.26, 3.27, 4.1, 4.4, 4.5, 4.6, 4.7
and 5.7 may be made at any time within the applicable statute of limitations;
(b) indemnification based upon Sections 14.1(b) through (d) and 14.2(b) through
(c) may be made at any time within the applicable statute of limitations; and
(c) the Shareholder shall not be required to indemnify Vision 21 or the
Subsidiary pursuant to Section 14.1 unless, and to the extent that, the
aggregate amount of Damages incurred by Vision 21 and/or the Subsidiary shall
exceed an amount equal to two percent (2%) of the total Purchase Price; and (c)
the Shareholder shall not be required to indemnify Vision 21 or the Subsidiary
with respect to a breach of a representation, warranty or covenant for Damages
in excess of the aggregate Purchase Price received by the Shareholder (other
than pursuant to a requirement to indemnify Vision 21 or the Subsidiary under
Sections 3.26 or 3.27, or unless the breach involves an intentional breach or
fraud by the Shareholder which shall be unlimited).

             14.7. Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds and such correlative insurance
benefit shall be net of the insurance premium, if any, that becomes due as a
result of such claim.

             14.8. Payment of Indemnification Obligation. In the event that the
Shareholder has an indemnification obligation to Vision 21 or the Subsidiary
hereunder, subject to Vision 21's


                                       49

<PAGE>   50



approval as set forth below, the Shareholder may satisfy such obligation by
transferring to Vision 21 or the Subsidiary (as the case may be) such number of
shares of Vision 21 Common Stock owned by the Shareholder having an aggregate
fair market value (which is the fair market value at such time based on the last
reported sale price of Vision 21 Common Stock on a principal national securities
exchange or other exchange on which the Vision 21 Common Stock is then listed or
the last quoted ask price on any over-the-counter market through which the
Vision 21 Common Stock is then quoted on the last trading day immediately
preceding the day on which the Shareholder transfers shares of Vision 21 Common
Stock to Vision 21 or the Subsidiary hereunder) equal to the indemnification
obligation, provided that each of the following conditions are satisfied:

                   a. The Shareholder shall transfer to Vision 21 or the
Subsidiary good, valid and marketable title to the shares of Vision 21 Common
Stock, free and clear of all adverse claims, security interests, liens, claims,
proxies, options, stockholders' agreements and encumbrances;

                   b. The Shareholder shall make such representation and
warranties as to title to the stock, absences of security interests, liens,
claims, proxies, stockholders' agreements and other encumbrances and other
matters as reasonably requested by Vision 21 or the Subsidiary; and

                   c. The other terms and conditions of any transaction
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21 or the
Subsidiary.

         15. TERMINATION.

             15.1. Termination. This Agreement may be terminated and the
Transaction may be abandoned:

                   a. at any time prior to the Closing Date by mutual agreement
of all parties;

                   b. at any time prior to the Closing Date by Vision 21 if any
representation or warranty of the Company or the Shareholder contained in this
Agreement or in any certificate or other document executed and delivered by the
Company or the Shareholder pursuant to this Agreement is or becomes untrue or
breached in any material respect or if the Company or the Shareholder fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt of written notice thereof;

                   c. at any time prior to the Closing Date by the Company if
any representation or warranty of Vision 21 or the Subsidiary contained in this
Agreement is or becomes untrue in any material respect or if Vision 21 or the
Subsidiary fails to comply in any


                                       50

<PAGE>   51



material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt or written notice thereof;

                    d. at any time prior to the Closing Date by the Company in
the event of the failure of any of the conditions precedent set forth in Article
11 of this Agreement;

                    e. at any time prior to the Closing Date by Vision 21 in the
event of the failure of any of the conditions precedent set forth in Article 10
of this Agreement;

                    f. by Vision 21 if at any time prior to the Closing Date,
Vision 21 deems termination to be advisable, provided, however, that if Vision
21 exercises its right to terminate this Agreement under this subsection, Vision
21 shall reimburse the Company and the Shareholder for all reasonable attorneys'
and accountants' fees incurred by the Company and the Shareholder in connection
with this Agreement; provided that Vision 21 shall only reimburse the Company
and the Shareholder up to an aggregate maximum amount of One Hundred Thousand
and No/100 Dollars ($100,000.00) for such fees; or

                    g. by Vision 21 or the Company if the Transaction shall not
have been consummated by November 30, 1997.

              15.2. Effect of Termination. In the event this Agreement is
terminated pursuant to Section 15.1, Vision 21, the Subsidiary, the Company and
the Shareholder, shall each be entitled to pursue, exercise and enforce any and
all remedies, rights, powers and privileges available at law or in equity,
subject to the limitations set forth in Section 15.1. In the event of a
termination of this Agreement under the provisions of this Article 15, a party
not then in material breach of this Agreement shall stand fully released and
discharged of any and all obligations under this Agreement.

         16. NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

             16.1. Shareholder and Company Non-Competition Covenant.

                   a. The Shareholder and the Company recognize that the
covenants of the Shareholder and the Company contained in this Section 16.1 are
an essential part of this Agreement and that, but for the agreement of the
Shareholder and the Company to comply with such covenants, Vision 21 and the
Subsidiary would not have entered into this Agreement. The Shareholder and the
Company acknowledge and agree that the Shareholder's and the Company's covenants
not to compete are necessary to ensure the continuation of the Subsidiary's and
Vision 21's respective Managed Care Businesses and are necessary to protect the
reputation of Vision 21 and the Subsidiary, and that irreparable and irrevocable
harm and damage will be done to Vision 21 and the Subsidiary if the Shareholder
or the Company compete with the Managed Care Businesses of Vision 21 or the
Subsidiary. The Shareholder and the Company accordingly agree


                                       51

<PAGE>   52



that for the periods set forth in the Business Management Agreement the
Shareholder and the Company shall not:

                      i)   directly or indirectly, either as principal, agent,
independent contractor, consultant, director, officer, employee, employer,
advisor, stockholder, partner or in any other individual or representative
capacity whatsoever, either for the Shareholder's or the Company's own benefit
or for the benefit of any other person or entity knowingly (A) hire, attempt to
hire, contact or solicit with respect to hiring any employee of Vision 21 (or of
the Subsidiary or of any of Vision 21's other direct or indirect subsidiaries)
or (B) induce or otherwise counsel, advise or encourage any employee of Vision
21 (or of the Subsidiary or of any of Vision 21's other direct or indirect
subsidiaries) to leave the employment of Vision 21;

                      ii)  act or serve, directly or indirectly, as a principal,
agent, independent contractor, consultant, director, officer, employee, employer
or advisor or in any other position or capacity with or for, or acquire a direct
or indirect ownership interest in or otherwise conduct (whether as stockholder,
partner, investor, joint venturer, or as owner of any other type of interest),
any Competing Managed Care Business as such term is defined herein; provided,
however, that this clause (ii) shall not prohibit the Shareholder or the Company
from being the owner of up to 1% of any class of outstanding securities of any
company or entity if such class of securities is publicly traded; or

                      iii) directly or indirectly, either as principal, agent,
independent, contractor, consultant, director, officer, employee, employer,
advisor, stockholder, partner or in any other individual or representative
capacity whatsoever, either for the Shareholder's or the Company's own benefit
or for the benefit of any other person or entity, call upon or solicit any
customers or clients of the Subsidiary's and Vision 21's respective Management
Businesses;

                   b. For the purposes of this Section 16.1, the term "Competing
Managed Care Business" shall mean an individual, business, corporation,
association, firm, undertaking, company, partnership, joint venture,
organization or other entity that either (A) conducts a business substantially
similar to the Subsidiary's or Vision 21's respective Managed Care Businesses
within the State, or (B) provides or sells a service which is the same or
substantially similar to, or otherwise competitive with the services provided by
the Subsidiary's or Vision 21's respective Managed Care Businesses within the
State; provided, however, that "Competing Management Business" shall not include
Vision 21, the Subsidiary or the Shareholder's internal management and
administration of the Shareholder's medical practice or participation in the
management and administration of a physician group in which the Shareholder
devotes a significant amount of time to the practice of medicine.

                   c. Should any portion of this Section 16.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Shareholder or the Company hereunder, and only in such
event, then the Shareholder, the Company, Vision 21 and the Subsidiary consent
and agree to such limitation on scope, duration or territory


                                       52

<PAGE>   53



as may be finally adjudicated as enforceable by a court of competent 
jurisdiction after the exhaustion of all appeals.

                   d. This covenant shall be construed as an agreement ancillary
to the other provisions of this Agreement, and the existence of any claim or
cause of action of the Shareholder or the Company against the Subsidiary or
Vision 21, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by Vision 21 or the Subsidiary of this
covenant; provided, however, that the Shareholder and the Company shall not be
bound by this covenant and shall not be obligated to pay the liquidated damages
contemplated in this Section 16.1 if at the time of a breach of this covenant
the Business Management Agreement has already been terminated pursuant to
Section 6.2(a) or 6.2(d) thereof. Without limiting other possible remedies to
Vision 21 and the Subsidiary for breach of this covenant, the Shareholder and
the Company agree that injunctive or other equitable relief will be available to
enforce the covenants of this provision. The Shareholder, the Company, Vision 21
and the Subsidiary further expressly acknowledge that the damages that would
result from a violation of this non-competition covenant would be impossible to
predict with any degree of certainty, and agree that liquidated damages in the
amount of the aggregate consideration received by the Company pursuant to this
Agreement is reasonable in light of the severe harm to the Subsidiary's or
Vision 21's respective Managed Care Businesses which would result in the event
that a violation of this non-competition covenant were to occur. If the
Shareholder or the Company violates this non-competition covenant, Vision 21
shall, in addition to all other rights and remedies available at law or equity,
be entitled to (a) cancel the number of shares of Common Stock held by the
Shareholder or the Company or, with respect to shares of Common Stock entitled
to be received by the Shareholder or the Company, terminate its obligation to
deliver such number of shares of Common Stock, and (b) repayment by Shareholder
to Vision 21 of the fair market value as described above, of Vision 21 Common
Stock sold by Shareholder; but in no event shall Vision 21 be entitled to offset
amounts in excess of the liquidated damages sum pursuant to this Section 16.1.
The Shareholder and the Company agree to deliver to Vision 21 the certificates
representing any such shares canceled by Vision 21. Payment and satisfaction by
Shareholder shall be made within sixty (60) days of notification to Shareholder
by Vision 21 that Shareholder has violated this non-competition covenant.

            16.2. Shareholder and Company Confidentiality Covenant. From the
date hereof, the Shareholder and the Company shall not, directly or indirectly,
use for any purpose, other than in connection with the performance of the
Shareholder's duties under the Shareholder's employment agreement with Sever,
Pusateri & Cortelli, M.D., P.A., or disclose to any third party, any material
information of Vision 21, the Subsidiary or the Company, as appropriate (whether
written or oral), including any business management or economic studies, patient
lists, proprietary forms, proprietary business or management methods, marketing
data, fee schedules, or trade secrets of Vision 21, the Subsidiary or of the
Company, as applicable, and including the terms and provisions of this Agreement
and any transaction or document executed by the parties pursuant to this
Agreement. Notwithstanding the foregoing, the Shareholder and the Company may
disclose information that the Shareholder or the Company can establish (a) is or
becomes generally available to and known by the public or medical community
(other than as a result of


                                       53

<PAGE>   54



an unpermitted disclosure directly or indirectly by the Shareholder or the
Company or their respective Affiliates, advisors, or representatives); (b) is or
becomes available to the Shareholder or the Company on a nonconfidential basis
from a source other than Vision 21, the Subsidiary, or their respective
Affiliates, advisors or representatives, provided that such source is not and
was not bound by a confidentiality agreement with or other obligation of secrecy
to Vision 21, the Subsidiary, or their respective Affiliates, advisors or
representatives of which the Shareholder or the Company has knowledge; or (c)
has already been or is hereafter independently acquired or developed by the
Shareholder or the Company without violating any confidentiality agreement with
or other obligation of secrecy to Vision 21, the Subsidiary, the Company or
their respective Affiliates, advisors or representatives. Without limiting the
other possible remedies to Vision 21 or the Subsidiary for the breach of this
covenant, the Shareholder and the Company agree that injunctive or other
equitable relief shall be available to enforce this covenant. The Shareholder
and the Company further agree that if any restriction contained in this Section
16.2 is held by any court to be unenforceable or unreasonable, a lesser
restriction shall be enforced in its place and the remaining restrictions
contained herein shall be enforced independently of each other.

             16.3. Survival. The parties acknowledge and agree that this Article
16 shall survive the Closing of the transactions contemplated herein.

         17. DISPUTES.

             17.1. Mediation and Arbitration. Any dispute, controversy or claim
(excluding claims arising out of an alleged breach of Article 16 of this
Agreement) arising out of this Agreement, or the breach thereof, that cannot be
settled through negotiation shall be settled (a) first, by the parties trying in
good faith to settle the dispute by mediation under the Commercial Mediation
Rules of the AAA (such mediation session to be held in Tampa, Florida, and to
commence within 15 days of the appointment of the mediator by the AAA), and (b)
if the controversy, claim or dispute cannot be settled by mediation, then by
arbitration administered by the AAA under its Commercial Arbitration Rules (such
arbitration to be held in Tampa, Florida, before a single arbitrator and to
commence within 15 days of the appointment of the arbitrator by the AAA), and
judgment on the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof.

         18. MISCELLANEOUS.

             18.1. Taxes. Shareholder and the Company shall pay all transfer
taxes, sales and other taxes and charges, imposed by the State, if any, which
may become payable in connection with the transactions and documents
contemplated hereunder. Vision 21 shall pay all transfer taxes, sales and other
taxes and charges imposed by the State of Florida, if any, which may become
payable in connection with the transactions and documents contemplated
hereunder.

             18.2. Remedies Not Exclusive. No remedy conferred by any of the
specific provisions of this Agreement or any document contemplated by this
Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in


                                       54

<PAGE>   55



addition to every other remedy given hereunder or now or hereafter existing at
law or in equity or by statute or otherwise. The election of any one or more
remedies by any party hereto shall not constitute a waiver of the right to
pursue other available remedies.

             18.3. Parties Bound. Except to the extent otherwise expressly
provided herein, this Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective heirs, representatives,
administrators, guardians, successors and assigns; and no other person shall
have any right, benefit or obligation hereunder.

and the rights of the parties determined in accordance with, the laws of the

subject of this Agreement, and as to those matters the law of the state of
incorporation or organization of the respective entity shall govern.

            18.6. Entire Agreement; Amendments and Waivers. This Agreement,
together with the documents contemplated by this Agreement and all Exhibits and
Schedules hereto and thereto, constitute the entire agreement between the
parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the parties, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter hereof. No

shall be binding unless it shall be specifically designated to be a supplement,
modification or waiver of this Agreement and shall be executed in writing by the
party to be bound thereby. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provision hereof
(whether or not similar), nor shall such waiver constitute a continuing waiver
unless otherwise expressly provided.

            18.7. Confidentiality Agreements. The provisions of any prior
confidentiality agreements and letters of intent between or among Vision 21, the
Company and the Shareholder, as amended, shall terminate and cease to be of any
force or effect at and upon the Closing.

            18.8. Modification Clause. It is the intention of the parties hereto
to conform strictly to applicable laws regarding the practice and regulation of
medicine, whether such laws are now or hereafter in effect, including the laws
of the United States of America, the State or any other applicable jurisdiction,
and including any subsequent revisions to, or judicial interpretations of, those
laws, in each case to the extent they are applicable to this Agreement (the
"Applicable Laws"). Accordingly, if the ownership of any Asset by the Subsidiary
violates any Applicable Law, then the parties hereto agree as follows: (a) the
provisions of this Section 18.8


                                       56

<PAGE>   57



shall govern and control; (b) if none of the parties hereto are materially
economically disadvantaged, then any Asset, the ownership of which violates any
Applicable Law, shall be deemed to have never been owned by the Subsidiary; (c)
if one or more of the parties hereto is materially economically disadvantaged,
then the parties hereto agree to negotiate in good faith such changes to the
structure and terms of the transactions provided for in this Agreement as may be
necessary to make these transactions, as restructured, lawful under applicable
laws and regulations, without materially disadvantaging either party; (d) this
Agreement shall be deemed modified and amended; and (e) the parties to this
Agreement shall execute and deliver all documents or instruments necessary to
effect or evidence the provisions of this Section 18.8.

            18.9.  Assignment. The Agreement may not be assigned by operation of
law or otherwise except that Vision 21 and the Subsidiary shall have the right
to assign this Agreement, at any time, to any Affiliate or direct or indirect
wholly-owned subsidiary. In the event of such assignment, Vision 21 and the
Subsidiary shall remain liable hereunder.

            18.10. Attorneys' Fees. Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to this
Agreement or the other documents contemplated with respect to the
interpretation, enforcement or breach hereof, the prevailing party in such
action shall be entitled to an award of all reasonable costs of litigation or
arbitration, including, without limitation, attorneys' fees, to be paid by the
losing party, in such amounts as may be determined by the court having
jurisdiction of such action or proceeding or by the arbitrators deciding such
action or proceeding or as agreed to by the parties hereto.

            18.11. Further Assurances. From time to time hereafter and without
further consideration, each of the parties hereto shall execute and deliver such
additional or further instruments of conveyance, assignment and transfer and
take such other actions as any of the other parties hereto may reasonably
request in order to more effectively consummate the transactions contemplated
hereunder or as shall be reasonably necessary or appropriate in connection with
the carrying out of the parties' respective obligations hereunder for the
purposes of this Agreement.

            18.12. Announcements and Press Releases. Any press releases or any
other public announcements concerning this Agreement or the transactions
contemplated hereunder shall be approved in advance by Vision 21; provided,
however, that if Shareholder or the Company reasonably believes that he or it
has a legal obligation to make a press release and the consent of Vision 21
cannot be obtained, then the release may be made without such approval.

            18.13. No Tax Representations. Each party acknowledges that it is
relying solely on its advisors to determine the tax consequences of the
transactions contemplated hereunder and that no representation or warranty has
been made by any party as to the tax consequences of such transactions except as
otherwise specifically set forth in this Agreement.

            18.14. No Rights as Stockholder. The Company and Shareholder shall
have no rights as a stockholder with respect to any shares of Common Stock until
the issuance of a stock


                                       57

<PAGE>   58



certificate evidencing such shares. Except as otherwise provided in the
Agreement, no adjustment shall be made for dividends or distributions or other
rights for which the record date is prior to such date any stock certificate is
issued.

            18.15. Multiple Counterparts. This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

            18.16. Headings. The headings of the several articles and sections
herein are inserted for convenience of reference only and are not intended to be
part of or to affect the meaning or interpretation of this Agreement.

            18.17. Severability. Each article, section and subsection of this
Agreement constitutes a separate and distinct undertaking, covenant or provision
of this Agreement. If any such provision shall finally be determined to be
unlawful, such provision shall be deemed severed from this Agreement, but every
other provision of this Agreement shall remain in full force and effect.

            18.18. Form of Transaction. If after the execution hereof, Vision 21
determines that the sale of the Assets of the Company can be better achieved
through a different form of transaction without economic injury to the Company
or the Shareholder, or delay of the consummation of the transaction, the Company
and the Shareholder shall cooperate in revising the structure of the transaction
and shall negotiate in good faith to so amend this Agreement; provided, that
Vision 21 shall reimburse the Company and the Shareholder at Closing for all
reasonable additional expenses incurred by the Company and the Shareholder as a
result of such change in form.

            18.19. Guaranty of Subsidiary's Obligations by Vision 21. Vision 21
hereby unconditionally guaranties all obligations of the Subsidiary to the
Company and the Shareholder contained within this Agreement.

                      AGREEMENT AND PLAN OF REORGANIZATION

         This Agreement and Plan of Reorganization (this "Agreement"), dated as
of September 1, 1997, is by and among RETINA ASSOCIATES SOUTHWEST, P.C., an
Arizona professional corporation (the "Company"), DENIS CARROLL, M.D., LEONARD
JOFFE, M.D. and REID SCHINDLER, M.D. (collectively, the "Physician"), and VISION
TWENTY-ONE, INC., a Florida corporation ("Vision 21").

                               R E C I T A L S

         A. Physician is a physician licensed to practice medicine in the State
(as defined herein) and currently employs ophthalmology employees and conducts
an ophthalmology practice through the Company and through optometrist employees
currently conducts an optometry practice through the Company.

         B. Physician owns all of the issued and outstanding shares of capital
stock of the Company.

         C. The Company and Vision 21 desire to effect a business combination
and merger of the Company with and into Vision 21 upon the terms and subject to
the satisfaction of the conditions precedent contained herein (the "Merger").

         D. It is intended that for federal income tax purposes the Merger shall
qualify as a reorganization within the meaning of Section 368(a)(1)(A) of the
Internal Revenue Code of 1986, as amended (the "Code").

         E. Vision 21 cannot acquire certain of the Company's assets because of
laws prohibiting general business corporations from engaging in the practice of
medicine or optometry, exercising control over physicians practicing medicine or
optometrists practicing optometry, or engaging in certain practices such as
fee-splitting with physicians or optometrists, and accordingly, the Company and
Vision 21 desire that the Company divest itself of such assets prior to the
Merger.

         F. Prior to the Merger, the Company intends to form a new professional
corporation ("New P.C.") to which it intends to transfer its medical and
optometry business, all of its Medical Assets (as defined herein) and all of the
Excluded Liabilities (as defined herein) in exchange for all of New P.C.'s
capital stock and to distribute such stock to Physician.

         G. New P.C. intends to employ the Physician and enter into a Business
Management Agreement (as defined herein) with the Company immediately prior to
the Merger; and

         H. As a result of the Merger, the Surviving Corporation (as defined
herein) will acquire the medical and optometry practice management business and
all of the Nonmedical

<PAGE>   2



Assets (as herein defined) of the Company associated with such business to the
extent permitted by law and assume all of Company's obligations under the
Business Management Agreement.

Company or, to the best knowledge of the Company, any other party to a material
Commitment, and no penalties have been incurred nor are amendments pending, with
respect to the material Commitments, except as described on Schedule 3.15. The
Commitments are in full force and effect and are valid and enforceable
obligations of the Company, and to the best knowledge of the Company, are valid
and enforceable obligations of the other parties thereto, in accordance with
their respective terms, and no defenses, off-sets or counterclaims have been
asserted or, to the best knowledge of the Company, may be made by any party

such default would not have a Material Adverse Effect on the business, (i)
neither the Company nor the Physician has received notice of any plan or
intention of any other party to any Commitment to exercise any right to cancel
or terminate any Commitment, and the Company does not know of any fact that
would justify the exercise of such a right; and (ii) neither the Company nor the

responsibility, and, to the best knowledge of the Company, are valid and
enforceable policies, except as may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally or the
availability of equitable remedies. All Insurance Policies shall be maintained
in force without interruption up to and including the Closing Date. True,
complete and correct copies of all Insurance Policies have been provided or made

Company nor the Physician has received any notice or other communication from
any issuer of any Insurance Policy cancelling such policy, materially increasing
any deductibles or retained amounts thereunder, and to the actual knowledge of

premiums is threatened. Except as set forth on Schedule 3.16, neither the
Company, the Physician nor any Professional Employee has any outstanding claims,
settlements or premiums owed against any Insurance Policy, and the Company, the
Physician and each Professional Employee has given all notices or has presented

application for any professional liability insurance coverage which has been
denied by an insurance agency or carrier, and the Company, the Physician and

Insurance Policy in excess of $10,000 per occurrence filed by the Company, the
Physician and each Professional Employee since January 1, 1994.

therefor, and all patents and applications therefor currently owned, in whole or
in part, by the Company, and all licenses, royalties, assignments and other

(including the expiration date thereof if applicable); and

                  b. all agreements relating to technology, know-how or
processes that the Company is licensed or authorized to use by others (other
than technology, know-how or processes generally available to other healthcare

The Company owns or has the legal right to use the Proprietary Rights, and to
the knowledge of the Company, such ownership or use does not conflict, infringe

consummation of the transactions contemplated hereby and the Proprietary Rights
are freely transferable. No claim has been asserted by any person to the
ownership of or for infringement by the Company of the proprietary right of any
other person, and the Company does not know of any valid basis for any such
claim. To the best knowledge

                                      -21-

the Company pending, or to the actual knowledge of the Company, threatened, and
the results of any completed audits are properly reflected in the Financial
Statements. The Company has not, to its best knowledge, violated any federal,
state, local or foreign tax law.

agencies.

                  f. Foreign Person. Neither the Company nor the Physician is a

documents contemplated herein by Vision 21 or the consummation by such party of
the transactions contemplated thereby, except for those consents or approvals
set forth on Schedule 5.6.

         5.7. Finder's Fee. Except as disclosed on Schedule 5.7, Vision 21 has
not incurred any obligation for any finder's, broker's or agent's fee in
connection with the transactions contemplated hereby.

         5.8. Capital Stock. The issuance and delivery by Vision 21 of shares of
Vision 21 Common Stock in connection with the Merger have been duly and validly
authorized by all necessary corporate action on the part of Vision 21. The
shares of Vision 21 Common Stock to be issued in connection with the Merger,
when issued in accordance with the terms of this Agreement, will be validly
issued, fully paid and nonassessable and will not have been issued in violation
of any preemptive rights, rights of first refusal or similar rights of any of
Vision 21's stockholders, or any federal or state law, including, without
limitation, the registration requirements of applicable federal and state
securities laws.

         5.9. Continuity of Business Enterprise. It is the present intention of
Vision 21 to continue at least one significant historic business line of the
Company, or to use at least a significant portion of the Company's historic
business assets in a business, in each case within the meaning of Treasury
Regulation Section 1.368-1(d).

         5.10. Vision 21 Financial Statements. The audited consolidated balance
sheet and related statements of income and cash flows of Vision 21 for its prior
three (3) full fiscal years, and its unaudited interim balance sheet for the six
month period ended June 30, 1997 and the related unaudited statement of income
of Vision 21 for the period then ended (collectively, with the related notes
thereto, the "Vision 21 Financial Statements"), (a) fairly present the financial
condition and results of operations of Vision 21 as of the dates and for the
periods indicated; and (b) have been prepared in conformity with GAAP (subject
to normal year-end adjustments and the absence of notes for any unaudited
interim financial statement), except as otherwise indicated in the Vision 21
Financial Statements.

         5.11. Liabilities and Obligations. Except as disclosed on Schedule
5.11, the Vision 21 Financial Statements shall reflect all material liabilities
of Vision 21, accrued, contingent or otherwise, that would be required to be
reflected on a balance sheet, or in the notes thereto, prepared in accordance
with GAAP. Except as set forth on Schedule 5.11 or in the Vision 21 Financial
Statements, Vision 21 is not liable upon or with respect to, or obligated in any
other way to provide funds in respect of or to guarantee or assume in any
manner, any debt, obligation

                                      -33-

or dividend of any person, corporation, association, partnership, joint venture,
trust or other entity, and Vision 21 does not know of any valid basis for the
assertion of any other claims or liabilities of any nature or in any amount.

         5.12. Compliance with Laws. Vision 21 has not failed to comply with any
applicable laws, regulations and licensing requirements or failed to file with
the proper authorities any necessary statements and reports except where the
failure to so comply or file would not, individually or in the aggregate, have a
material adverse effect on the Merger. There are no existing violations by
Vision 21 of any federal, state or local law or regulation that could,
individually or in the aggregate, have a material adverse effect on the Merger.
Vision 21 possesses all necessary licenses, franchises, permits and governmental
authorizations for the conduct of Vision 21's business as now conducted and
after the Closing, as contemplated in this Agreement and the Business Management
Agreement, except for such licenses, franchises, permits or governmental
authorizations which, if not possessed by Vision 21, would not have a material
adverse effect on the business of Vision 21. The transactions contemplated by
this Agreement will not result in a default under or a breach or violation of,
or adversely affect the rights and benefits afforded by any such licenses,
franchises, permits or government authorizations, except for any such default,
breach or violation that would not, individually or in the aggregate, have a
material adverse effect on the Merger or the performance of the services
contemplated under the Business Management Agreement. Since January 1, 1993,
Vision 21 has not received any notice from any federal, state or other
governmental authority or agency having jurisdiction over its properties or
activities, or any insurance or inspection body, that its operations or any of
its properties, facilities, equipment, or business practices fail to comply with
any applicable law, ordinance, regulation, building or zoning law, or
requirement of any public or quasi-public authority or body, except where
failure to so comply would not, individually or in the aggregate, have a
material adverse effect on the Merger.

         5.13. Insolvency Proceedings. Vision 21 is not currently under the
jurisdiction of a Federal or state court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

         5.14. Equal Exchange. Vision 21 believes that the fair market value of
all the Company Common Stock shall be approximately equal to the fair market
value of the Merger Consideration at the Effective Time.

         5.15. Employment of Company's Employees. Vision 21 does not currently
intend to change the existing composition or employment terms of any of the
non-professional personnel which have employment arrangements with the Company
on the effective date of this Agreement (except as is necessary for Vision 21 to
employ such individuals pursuant to the Business Management Agreement). Vision
21 reserves the right, however, to change the number, composition or employment
terms of such non-professional personnel in the future.

         6. CLOSING DATE REPRESENTATIONS AND WARRANTIES OF THE PHYSICIAN. The
Physician represents and warrants that, except as disclosed in the Schedules,

         6.1. Organization and Good Standing; Qualification. New P.C. is a
professional corporation duly organized, validly existing and in good standing
under the laws of the State, with all requisite corporate power and authority to
carry on the business in which it intends to engage, to own the properties it
intends to own, and to execute and deliver the Business Management Agreement and
the Physician Employment Agreements and consummate the transactions and perform
the services contemplated thereby. New P.C. is duly qualified and licensed to do

issued and outstanding, and no shares of capital stock of New P.C. are held in

P.C.'s common stock, free and clear of all security interests, liens, adverse
claims, encumbrances, equities, proxies and shareholders' agreements. Each
outstanding share of New P.C.'s common stock has been legally and validly issued
and is fully paid and nonassessable. There exist no options, warrants,
subscriptions or other rights to purchase, or securities convertible into or
exchangeable for, any of the authorized or outstanding securities of New P.C. No

performance by New P.C. of the Business Management Agreement, the Physician
Employment Agreements, the Optometrist Employment Agreements and the other
agreements contemplated thereby, and the consummation of the transactions and
provisions of services contemplated thereby, have been duly authorized by New
P.C. The Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements and each other agreement contemplated thereby
will be as of the Closing Date duly executed and delivered by New P.C. and will
constitute legal, valid and binding obligations of New P.C. enforceable against
New P.C. in accordance with their respective terms, except as may be limited by
applicable bankruptcy, insolvency or similar laws affecting creditors' rights
generally or the availability of equitable remedies.

<PAGE>   36




         6.5. No Violation. Neither the execution, delivery or performance of
the Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements or the other agreements contemplated thereby
nor the consummation of the transactions or provision of services contemplated
thereby will (a) conflict with, or result in a violation or breach of the terms,
conditions or provisions of, or constitute a default under, the Articles or
Certificate of Incorporation or Bylaws of New P.C., or (b) to the actual
knowledge of the Physician, violate or conflict with any judgment, decree,
order, statute, rule or regulation of any court or any public, governmental or
regulatory agency or body.

         6.6. No Business, Agreements, Assets or Liabilities. New P.C. has not
commenced business since its incorporation. Other than its Articles or
Certificate of Incorporation and Bylaws, and as of the Closing Date, the
Business Management Agreement, the Physician Employment Agreements, the
Optometrist Employment Agreements, the Employee Benefit Plans and the other
contracts or agreements listed on Schedule 6.6, New P.C. is not a party to or

liabilities, accrued, contingent or otherwise (known or unknown and asserted or
unasserted).

         6.7. Compliance with Laws. New P.C. has complied with all applicable
laws, regulations and licensing requirements and has filed with the proper
authorities all necessary statements and reports, except where failure to so
comply or file would not, individually or in the aggregate, have a material
adverse effect on the business, operations or financial condition of New P.C.

         7. SECURITIES LAW MATTERS.

         7.1. Investment Representations and Covenants of Physician.

                  a. Physician understands that the Securities will not be
registered under the Securities Act or any state securities laws on the grounds
that the issuance of the Securities is exempt from registration pursuant to
Section 4(2) of the Securities Act under the Securities Act and applicable state
securities laws, and that the reliance of Vision 21 on such exemptions is
predicated in part on the Physician's representations, warranties, covenants and
acknowledgements set forth in this Section.

                  b. Except as disclosed on Schedule 7.1(b) attached hereto,
Physician represents and warrants that Physician is an "accredited investor" or
"sophisticated investor" as defined under the Securities Act and state "Blue
Sky" laws, or that Physician has utilized, to the extent necessary to be deemed
a sophisticated investor under the Securities Act and State "Blue Sky" laws, the
assistance of a professional advisor.

                  c. Physician represents and warrants that the Securities to be
acquired by Physician upon consummation of the transactions described in this
Agreement will be acquired

                                      -36-

<PAGE>   37



by Physician for Physician's own account, not as a nominee or agent, and without
a view to resale or other distribution within the meaning of the Securities Act
and the rules and regulations thereunder, except as contemplated in this
Agreement, and that Physician will not distribute any of the Securities in
violation of the Securities Act. All Securities shall bear a restrictive legend
in substantially the following form:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY ONLY BE SOLD OR OTHERWISE
         TRANSFERRED IF THE HOLDER HEREOF COMPLIES WITH THE ACT AND APPLICABLE
         SECURITIES LAWS."

         In addition, the Securities shall bear any legend required by the
securities or "Blue Sky" laws of any state where Physician resides as well as
any other legend deemed appropriate by Vision 21 or its counsel.

                  d. Physician represents and warrants that the address set
forth below Physician's name on Schedule 7.1(d) is Physician's principal
residence.

                  e. Physician (i) acknowledges that the Securities issued to
Physician at the Closing must be held indefinitely by Physician unless
subsequently registered under the Securities Act or an exemption from
registration is available, (ii) is aware that any routine sales of Securities
made pursuant to Rule 144 under the Securities Act may be made only in limited
amounts and in accordance with the terms and conditions of that Rule and that in
such cases where the Rule is not applicable, compliance with some other
registration exemption will be required, and (iii) is aware that Rule 144 is not
currently available for use by Physician for resale of any of the Securities to
be acquired by Physician upon consummation of the transactions described in this
Agreement.

                  f. Physician represents and warrants to Vision 21 that
Physician, either alone or together with the assistance of Physician's own
professional advisor, has such knowledge and experience in financial and
business matters such that Physician is capable of evaluating the merits and
risks of Physician's investment in any of the Securities to be acquired by
Physician upon consummation of the transactions described in this Agreement.

                  g. Physician confirms that Physician has had the opportunity
to ask questions of and receive answers from Vision 21 concerning the terms and
conditions of Physician's investment in the Securities, and the Physician has
received to Physician's satisfaction, such additional information, in addition
to that set forth herein, about Vision 21's operations and the terms and
conditions of the offering as Physician has requested.

                  h. In order to ensure compliance with the provisions of
paragraph (c) hereof, Physician agrees that after the Closing Physician will not
sell or otherwise transfer or dispose of Securities or any interest therein
(unless such shares have been registered under the

                                      -37-

<PAGE>   38



Securities Act) without first complying with either of the following conditions,
the expenses and costs of satisfaction of which shall be fully borne and paid
for by Physician:

                           i) Vision 21 shall have received a written legal
opinion from legal counsel, which opinion and counsel shall be satisfactory to
Vision 21 in the exercise of its reasonable judgment, or a copy of a
"no-action" or interpretive letter of the Securities and Exchange Commission
specifying the nature and circumstances of the proposed transfer and indicating
that the proposed transfer will not be in violation of any of the registration
provisions of the Securities Act and the rules and regulations promulgated
thereunder; or

                           ii) Vision 21 shall have received an opinion from its
own counsel to the effect that the proposed transfer will not be in violation
of any of the registration provisions of the Securities Act and the rules and
regulations promulgated thereunder.

Physician also agrees that the certificates or instruments representing the
Securities to be issued to Physician pursuant to this Agreement may contain a
restrictive legend noting the restrictions on transfer described in this Section
and required by federal and applicable state securities laws, and that
appropriate "stop-transfer" instructions will be given to Vision 21's transfer
agent, if any, provided that this Section 7.1(h) shall no longer be applicable
to any Securities following their transfer pursuant to a registration statement
effective under the Securities Act or in compliance with Rule 144 or if the
opinion of counsel referred to above is to the further effect that transfer
restrictions and the legend referred to herein are no longer required in order
to establish compliance with any provisions of the Securities Act.

                  i. Physician understands that there can be no assurance that a
Public Offering by Vision 21 will ever occur or if it does occur that it will be
successful.

                  j. Physician agrees that he shall be considered an "affiliate"
of Vision 21 for purposes of Rule 144 and agrees to the restrictions and
limitations imposed by Rule 144 on affiliates. Physician further agrees that he
shall be considered an affiliate of Vision 21 for Rule 144 purposes even if he
does not meet the technical definition of "affiliate" under Rule 144.

         7.2. Current Public Information. At all times following the
registration of any of Vision 21's securities under the Securities Act or
Exchange Act pursuant to which Vision 21 becomes subject to the reporting
requirements of the Exchange Act, Vision 21 shall use commercially reasonable
efforts to comply with the requirements of Rule 144 under the Securities Act, as
such Rule may be amended from time to time (or any similar rule or regulation
hereafter adopted by the SEC) regarding the availability of current public
information to the extent required to enable any holder of shares of Common
Stock to sell such shares without registration under the Securities Act pursuant
to Rule 144 (or any similar rule or regulation).

soon thereafter as may be practical. Effective at the time of Closing, the
Company shall cause New P.C. to assume all of the obligations of the Company as
the sponsoring employer and/or plan administrator of the Retirement Plan in
compliance with applicable law.

         Subsequent to Closing, New P.C. and Vision 21 shall review the extent
to which New P.C. can resume contributions to the Retirement Plan without
violating the qualification requirements of Sections 410(b) and 401(a)(4) of the
Code taking into account any employees of Vision 21 who would be "leased
employees" of New P.C. under Section 414(n) of the Code. If Vision 21 and New
P.C. mutually agree that such qualification requirements can be satisfied, New
P.C. may elect to continue the Retirement Plan and make contributions in
accordance with its terms, provided that New P.C. shall agree to cover at its
own expense any Vision 21 employees who are leased employees if such coverage is
required to maintain the tax-qualified status of the Retirement Plan.

         8.19. Delivery of Schedules. The Company and the Physician shall
deliver to Vision 21 all Schedules required to be delivered by them prior to the
Closing.

         8.20. Conversion of Company. After the transfer of the Medical Assets
of the Company to New P.C. and the assumption of the Excluded Liabilities by New
P.C. and prior to Closing, Physician shall cause the Company to take such action
and file such documents or instruments as may be necessary to convert the
Company into a general business corporation in accordance with applicable law.

         8.21. Assignment of Fees for Medical and Optometry Services. On or
prior to the Closing Date, the Company shall obtain an irrevocable assignment
from all Professional Employees of any and all of their rights to receive
payment for the provision of ophthalmology or optometry services which are part
of the Accounts Receivable to the Company existing on the Closing Date, except
for those fees specified and set forth on Schedule 8.21. Each Professional
Employee shall undertake to endorse any payments received on account of such
services to the order of the Company and to take such other action as may be
necessary to confirm to the Company the rights to collect and retain for its own
account such Accounts Receivable. The Company shall cause its Professional
Employees to agree that such security interest of such lender(s) is intended to
be a first priority security interest and is superior to any right, title or
interest which may be asserted by such Professional Employees with respect to
the Accounts Receivable or the proceeds thereof. In the event that the
assignment of rights described in this Section shall be deemed, for any reason,
to be ineffective as an outright assignment, the Company shall cause each
Professional Employee to agree that such Professional Employee shall be deemed,
effective as of the Closing Date, to have granted to the Company a first
priority lien on and security interest in and to any and all interests of such
Professional Employee in any of the Accounts Receivable, and all proceeds with
respect thereto, to secure the collection by the Company of all Accounts
Receivable, and this Agreement shall be deemed to be a security agreement to the
extent necessary to give effect to the foregoing. The Company shall cause each

                                      -43-

Professional Employee to execute and deliver, all such financing statements as
the Company or Vision 21 may request in order to perfect such security interest.
The Company shall not suffer any Professional Employee to grant any other lien
on or security interest in or to such Accounts Receivable or any proceeds
thereof.

         9. COVENANTS OF VISION 21. Vision 21 agrees that between the date
hereof and the Closing:

         9.1. Consummation of Agreement. Vision 21 shall use its best efforts to
cause the consummation of the transactions contemplated hereby in accordance

necessary to approve the Merger; provided, however, that this covenant shall not

         9.2. Efforts to Effect. Vision 21 will use its best efforts to take, or

this Agreement and prior to the Effective Time under any agreement or commitment
entered into by Vision 21 material to Vision 21's condition (financial or
otherwise), operations, assets, liabilities or business and to which it is
subject; or (b) any material adverse change in Vision 21's condition (financial
or otherwise), operations, assets, liabilities or business.

         9.4. Approvals of Third Parties. Vision 21 shall use its best efforts
to secure, as soon as practicable after the date hereof, all necessary approvals
and consents of third parties to the consummation of the transactions
contemplated hereby.

obtain all licenses, permits, approvals or other authorizations required under
any law, statute, rule, regulation or ordinance, or otherwise necessary or
desirable to consummate the transactions or provide the services contemplated by
the Business Management Agreement and to conduct the intended business of Vision
21.

         9.6. Release of Physician From Practice Liabilities. Vision 21 shall
use its best efforts to obtain from third party creditors the release of
Physician from any personal liabilities relating to the Practice which are
identified on Schedule 9.6 and assumed by Vision 21 pursuant to the terms of
this Agreement.

         10. COVENANTS OF VISION 21, THE COMPANY AND THE PHYSICIAN. Vision 21,
the Company and the Physician agree as follows (with respect to New P.C.'s
covenants, the Physician agrees to cause New P.C. to perform):

         10.1. Amendment of Schedules. Each party hereto agrees that, with
respect to the representations and warranties of such party contained in this
Agreement, such party shall have the continuing obligation until the Closing to
attach, supplement or amend promptly the Schedules with respect to any matter
that would have been or would be required to be set forth or described in the
Schedules in order to not materially breach any representation, warranty or
covenant of such party contained herein; provided that no amendment or
supplement to a Schedule that constitutes or reflects a material adverse change

such amendment or supplement, and no amendment or supplement to a Schedule that
constitutes or reflects a material adverse change to Vision 21 may be made
unless the Company and the Physician consent to such amendment or supplement.
For all purposes of this Agreement, including without limitation for purposes of
determining whether the conditions set forth in Sections 11.1 and 12.1 have been
fulfilled, the Schedules hereto shall be deemed to be the Schedules as amended
or supplemented pursuant to this Section 10.1. In the event that the Company is
required to amend or supplement a Schedule in accordance with this Section 10.1
and Vision 21 does not consent to such amendment or supplement, or Vision 21 is
required to amend or supplement a Schedule in accordance with this Section 10.1
and the Company and the Physician do not consent, this Agreement shall be deemed
terminated by mutual consent as set forth in Section 16.1(d) or Section 16.1(e)
as appropriate.

         10.2. Business Management Agreement. The Company and the Physician
shall use their best efforts to cause the Business Management Agreement to be
executed and delivered by New P.C. on or prior to the Closing Date, which shall
be considered a Nonmedical Asset of the Company and shall be acquired by Vision
21 in the Merger.

         10.3. Fees and Expenses.

("Prepared Audit Materials") shall be for use solely by Vision 21; provided,
however, that the Company may utilize the Prepared Audit Materials solely in
connection with its review of Vision 21's calculation of the Merger
Consideration. The Prepared Audit Materials shall not be deemed to include those
items which customarily remain the property of auditors such as their working
papers and memos.

                  b. In the event the Merger is not consummated, the Company
shall pay for or reimburse Vision 21 for the expenses of the Accountants in
connection with the Audit. The Company and Physician shall not be entitled to

Physician pays for or reimburses Vision 21 for such audit expenses in advance of
receiving the Medicare audit materials (either from Vision 21 or its
Accountants). If the Merger is not consummated, the Company shall pay for all
expenses incurred in connection with the medicare audit.

                  d. Each of the Company, Physician and Vision 21 shall pay the

Physician to an amount less than fifty percent (50%) of (a) the fair value of
the Company Common Stock held by the Physician immediately before the Effective
Time of the Merger, plus (b) the value of any contingent consideration received
by the Company in connection with the Merger, unless the Physician obtains an
opinion of counsel reasonably satisfactory to Vision 21 that such transfer will
not violate the continuity of shareholder interest requirement set forth in
Treas. Reg. Section 1.388-1. In the event that Physician wishes to dispose of
any shares of Vision 21 Common Stock received in the Merger within such two (2)
year period, Physician shall provide written notice to Vision 21, not less than
ten (10) days prior to the intended date of disposition, specifying the number
of shares of which the Physician proposes to dispose.

         15. REMEDIES.

         15.1. Indemnification by the Physician. Subject to the terms and
conditions of this Agreement, the Physician agrees to indemnify, defend and hold
Vision 21, the Surviving Corporation and their respective directors, officers,
employees, agents, attorneys and affiliates harmless from and against all
losses, claims, obligations, demands, assessments, penalties, liabilities,
costs, damages, reasonable attorneys' fees and expenses (collectively,
"Damages") asserted against or incurred by such entities and individuals
(including, but not limited to, any reduction in payments to or revenues of New
P.C.), arising out of or resulting from:

                  a. a breach of any representation, warranty or covenant of the
Company or the Physician contained herein or in any schedule or certificate
delivered hereunder;

                  b. any liability under the Securities Act, the Exchange Act or
any other federal or state "Blue Sky" or securities law or regulation, at common
law or otherwise, (i) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact relating to the Physician, the
Company (including its subsidiaries, if any) or New P.C., and provided to Vision
21 or its counsel by the Company or the Physician, specifically for inclusion in
a Registration Statement or any prospectus forming a part thereof, or any
amendment thereof or supplement thereto, (ii) arising out of or based upon any
omission or alleged omission to state therein a material fact relating to the
Physician, the Company (including its subsidiaries, if any) or New P.C. required
to be stated therein or necessary to make the statements therein not misleading,
and not provided to Vision 21 or its counsel by the Company or the Physician,
provided, however, that such indemnity shall not inure to the benefit of Vision
21 to the extent that such untrue statement (or alleged untrue statement) was
made, in, or omission (or alleged omission) occurred in, any preliminary
prospectus, and such information was not so included by Vision 21 and properly
delivered to shareholders of Vision 21 who acquire Vision 21 Common Stock in any
Public Offering;

                  c. any filings, reports or disclosures made pursuant to the
IRS Voluntary Compliance Resolution Program, if applicable;

                                      -53-

<PAGE>   54




                  d. any failure of the Merger to qualify as a reorganization
within the meaning of Section 368(a)(1)(A) or Section 368(a)(2)(D) of the Code;

                  e. any liability arising from the spin off of the Company's
medical business and Medical Assets; and

                  f. any liability arising from any alleged unlawful sale or
offer to sell or transfer any of the Common Stock by Physician.

         15.2. Indemnification by Vision 21. Subject to the terms and conditions
of this Agreement, Vision 21 hereby agrees to indemnify, defend and hold the
Physician harmless from and against all damages asserted against or incurred by
him arising out of or resulting from:

                  a. a breach by Vision 21 of any representation, warranty or
covenant of Vision 21 contained therein or in any schedule or certificate
delivered hereunder;

                  b. any liability under the Securities Act, the Exchange Act or
any other federal or state "Blue Sky" or securities law or regulation, at common
law or otherwise, arising out of or based upon any untrue statement or alleged
untrue statement of a material fact relating to Vision 21, contained in any
preliminary prospectus, Registration Statement or any prospectus forming a part
thereof, or any amendment thereof or supplement thereto, arising out of or based
upon any omission or alleged omission to state therein a material fact relating
to Vision 21 (including its subsidiaries), required to be stated therein or
necessary to make the statements therein not misleading; and

                  c. any filings, reports or disclosures made pursuant to the
IRS Voluntary Compliance Resolution Program, if applicable.

         Notwithstanding anything in this Section 15.2, Vision 21 shall not be
liable for any Damages resulting from any matter not disclosed to Vision 21 by
any of the third parties acquired by Vision 21 in connection with Recent
Acquisitions.

         15.3. Conditions of Indemnification. All claims for indemnification
under this Agreement shall be asserted and resolved as follows:

                  a. A party claiming indemnification under this Agreement (an
"Indemnified Party") shall promptly (and, in any event, at least ten (10) days
prior to the due date for any responsive pleadings, filings or other documents)
(i) notify the party from whom indemnification is sought (the "Indemnifying
Party") of any third-party claim or claims asserted against the Indemnified
Party ("Third Party Claim") that could give rise to a right of indemnification
under this Agreement and (ii) transmit to the Indemnifying Party a written
notice ("Claim Notice") describing in reasonable detail the nature of the Third
Party Claim, a copy of all papers served with respect to such claim (if any), an
estimate of the amount of damages attributable to the Third Party Claim and the
basis of the Indemnified Party's request for

                                      -54-

<PAGE>   55



indemnification under this Agreement. Except as set forth in Section 15.6, the
failure to promptly deliver a Claim Notice shall not relieve the Indemnifying
Party of its obligations to the Indemnified Party with respect to the related
Third Party Claim except to the extent that the resulting delay is materially
prejudicial to the defense of such claim. Within thirty (30) days after receipt
of any Claim Notice (the "Election Period"), the Indemnifying Party shall notify
the Indemnified Party (i) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article 15 with respect to such
Third Party Claim and (ii) whether the Indemnifying Party desires, at the sole
cost and expense of the Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

                     If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 15.3(b). The Indemnifying
Party shall have full control of such defense and proceedings, including any
compromise or settlement thereof. The Indemnified Party is hereby authorized, at
the sole cost and expense of the Indemnifying Party (but only if the Indemnified
Party is entitled to indemnification hereunder), to file, during the Election
Period, any motion, answer or other pleadings that the Indemnified Party shall
deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being
understood and agreed that if an Indemnified Party takes any such action that is
prejudicial and causes a final adjudication that is adverse to the Indemnifying
Party, the Indemnifying Party shall be relieved of its obligations hereunder
with respect to such Third Party Claim). If requested by the Indemnifying Party,
the Indemnified Party agrees, at the sole cost and expense of the Indemnifying
Party, to cooperate with the Indemnifying Party and its counsel in contesting
any Third Party Claim that the Indemnifying Party elects to contest, including,
without limitation, the making of any related counterclaim against the person
asserting the Third Party Claim or any cross-complaint against any person. The
Indemnified Party may participate in, but not control, any defense or settlement
of any Third Party Claim controlled by the Indemnifying Party pursuant to
Section 15.3(b) and shall bear its own costs and expenses with respect to such
participation; provided, however, that if the named parties to any such action
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and the Indemnified Party has been advised by counsel that
there may be one or more legal defenses available to it that are different from
or additional to those available to the Indemnifying Party, then the Indemnified
Party may employ separate counsel at the expense of the Indemnifying Party, and
upon written notification thereof, the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of the Indemnified Party;
provided further that the Indemnifying Party shall not, in connection with any
one such action or separate but substantially similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances,
be liable for the reasonable fees and expenses of more than one separate firm of
attorneys at any time for the Indemnified Party, which firm shall be designated
in writing by the Indemnified Party.

<PAGE>   56



                  b. If the Indemnifying Party fails to notify the Indemnified
Party within the Election Period that the Indemnifying Party elects to defend
the Indemnified Party pursuant to Section 15.3(b), or if the Indemnifying Party
elects to defend the Indemnified Party pursuant to Section 15.3(b) but fails
diligently and promptly to prosecute or settle the Third Party Claim, then the
Indemnified Party shall have the right to defend, at the sole cost and expense
of the Indemnifying Party (if the Indemnified Party is entitled to
indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to the Indemnified Party to the effect that
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article 15 and if such dispute is resolved in favor of the
Indemnifying Party, the Indemnifying Party shall not be required to bear the
costs and expenses of the Indemnifying Party's defense pursuant to this Section
or of the Indemnifying Party's participation therein at the Indemnified Party's
request, and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control any defense or settlement controlled by the
Indemnified Party pursuant to this Section 15.3(c), and the Indemnifying Party
shall bear its own costs and expenses with respect to such participation;
provided, however, that if the named parties to any such action (including any
impleaded parties) include both the Indemnifying Party and the Indemnified
Party, and the Indemnifying Party has been advised by counsel that there may be
one or more legal defenses available to the Indemnified Party, then the
Indemnifying Party may employ separate counsel and upon written notification
thereof, the Indemnified Party shall not have the right to assume the defense of
such action on behalf of the Indemnifying Party.

                  c. In the event any Indemnified Party should have a claim
against any Indemnifying Party hereunder that does not involve a Third Party
Claim, the Indemnified Party shall transmit to the Indemnifying Party a written
notice (the "Indemnity Notice") describing in reasonable detail the nature of
the claim, an estimate of the amount of damages attributable to such claim and
the basis of the Indemnified Party's request for indemnification under this
Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 19.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  d. Payments of all amounts owing by an Indemnifying Party
pursuant to this Article 15 relating to a Third Party Claim shall be made within
thirty (30) days after the latest of (i) the settlement of such Third Party
Claim, (ii) the expiration of the period for appeal of a final adjudication of
such Third Party Claim or (iii) the expiration of the period for appeal

                                      -56-

<PAGE>   57



of a final adjudication of the Indemnifying Party's liability to the Indemnified
Party under this Agreement. Payments of all amounts owing by an Indemnifying
Party pursuant to Section 15.3(d) shall be made within thirty (30) days after
the later of (i) the expiration of the sixty (60) day Indemnity Notice period or
(ii) the expiration of the period for appeal, if any, of a final adjudication or
arbitration of the Indemnifying Party's liability to the Indemnified Party under
this Agreement.

         15.4. Remedies Not Exclusive. The remedies provided in this Agreement
shall not be exclusive of any other rights or remedies available to one party
against the other, either at law or in equity. This Article 15 regarding
indemnification shall survive Closing.

         15.5. Costs, Expenses and Legal Fees. Each party hereto agrees to pay
the costs and expenses (including attorneys' fees and expenses) incurred by the
other parties in successfully (a) enforcing any of the terms of this Agreement,
or (b) proving that another party breached any of the terms of this Agreement.

         15.6. Indemnification Limitations. Notwithstanding the provisions of
Sections 15.1 and 16.2, (a) no party shall be required to indemnify another
party with respect to a breach of a representation, warranty or covenant unless
the claim for indemnification is brought within two (2) years after the Closing
Date, except that a claim for indemnification for a breach of the
representations and warranties contained in Sections 3.1, 3.2, 3.3., 3.4, 3.5,
3.6, 3.14, 3.17, 3.20, 3.23, 4.1, 4.3, 4.4, 4.8, 5.1, 5.2, 5.3, 5.4, 5.6, 5.7,
6.1, 6.2, 6.3 and 6.4 may be made at any time, and a claim for indemnification
for a breach of the representations and warranties contained in Sections 3.12,
3.18, 3.21, 3.27, 3.28, 3.29, 3.30, 3.31, 3.33, 4.5, 4.7, 4.11, 5.8 and 7.1 may
be made at any time within the applicable statute of limitations; (b)
indemnification based upon Sections 15.1(b) through (f) and 15.2(b) may be made
at any time within the applicable statute of limitations; and (c) the Physician
shall not be required to indemnify Vision 21 pursuant to Section 15.1 unless,
and to the extent that, the aggregate amount of Damages incurred by Vision 21
shall exceed an amount equal to two percent (2%) of the total Merger
Consideration; and (d) the Physician shall not be required to indemnify Vision
21 with respect to a breach of a representation, warranty or covenant for
Damages in excess of the aggregate Merger Consideration received by the
Physician (other than pursuant to a requirement to indemnify Vision 21 under
Sections 3.30 and 3.31, or unless the breach involves an intentional breach or
fraud by the Physician or the Company, which shall be unlimited).

         15.7. Tax Benefits; Insurance Proceeds. The total amount of any
indemnity payments owed by one party to another party to this Agreement shall be
reduced by any correlative tax benefit received by the party to be indemnified
or the net proceeds received by the party to be indemnified with respect to
recovery from third parties or insurance proceeds and such correlative insurance
benefit shall be net of the insurance premium, if any, that becomes due as a
result of such claim.

         15.8. Payment of Indemnification Obligation. In the event that the
Physician has an indemnification obligation to Vision 21 hereunder, subject to
Vision 21's approval as set forth

                                      -57-

<PAGE>   58



below, the Physician may satisfy such obligation by transferring to Vision 21
such number of shares of Vision 21 Common Stock owned by the Physician having an
aggregate fair market value (which is the fair market value at such time based
on the last reported sale price of Vision 21 Common Stock on a principal
national securities exchange or other exchange on which the Vision 21 Common
Stock is then listed or the last quoted ask price on any over-the-counter market
through which the Vision 21 Common Stock is then quoted on the last trading day
immediately preceding the day on which the Physician transfers shares of Vision
21 Common Stock to Vision 21 hereunder) equal to the indemnification obligation,
provided that each of the following conditions are satisfied:

                  a. The Physician shall transfer to Vision 21 good, valid and
marketable title to the shares of Vision 21 Common Stock, free and clear of all
adverse claims, security interests, liens, claims, proxies, options,
stockholders' agreements and encumbrances;

                  b. The Physician shall make such representation and warranties
as to title to the stock, absences of security interests, liens, claims,
proxies, stockholders' agreements and other encumbrances and other matters as
reasonably requested by Vision 21; and

                  c. The other terms and conditions of any transaction 
contemplated pursuant to this Section and the effects thereof, including any
legal or tax consequences, shall be reasonably satisfactory to Vision 21.

         16. TERMINATION.

         16.1. Termination. This Agreement may be terminated and the Merger may
be abandoned:

                  a. at any time prior to the Closing Date by mutual agreement
of all parties;

                  b. at any time prior to the Closing Date by Vision 21 if any
representation or warranty of the Company or the Physician contained in this
Agreement or in any certificate or other document executed and delivered by the
Company or the Physician pursuant to this Agreement is or becomes untrue or
breached in any material respect or if the Company or the Physician fails to
comply in any material respect with any covenant or agreement contained herein,
and any such misrepresentation, noncompliance or breach is not cured, waived or
eliminated within twenty (20) days after receipt of written notice thereof;

                  c. at any time prior to the Closing Date by the Company if any
representation or warranty of Vision 21 contained in this Agreement is or
becomes untrue in any material respect or if Vision 21 fails to comply in any
material respect with any covenant or agreement contained herein, and any such
misrepresentation, noncompliance or breach is not cured, waived or eliminated
within twenty (20) days after receipt or written notice thereof;


                                      -58-

<PAGE>   59



                  d. at any time prior to the Closing Date by the Company in the
event of the failure of any of the conditions precedent set forth in Article 13
of this Agreement;

                  e. at any time prior to the Closing Date by Vision 21 in the
event of the failure of any of the conditions precedent set forth in Article 12
of this Agreement;

                  f. by Vision 21 if at any time prior to the Closing Date,
Vision 21 deems termination to be advisable, provided, however, that if Vision
21 exercises its right to terminate this Agreement under this subsection, Vision
21 shall reimburse the Company and the Physician for all reasonable attorneys'
and accountants' fees incurred by the Company and the Physician in connection
with this Agreement; provided that Vision 21 shall only reimburse the Company
and the Physician up to an aggregate maximum amount of One Hundred Thousand and
No/100 Dollars ($100,000.00) for such fees; or

                  g. by Vision 21 or the Company if the Merger shall not have
been consummated by October 31, 1997.

         16.2. Effect of Termination. In the event this Agreement is terminated
pursuant to Section 16.1, Vision 21, the Company and the Physician, shall each
be entitled to pursue, exercise and enforce any and all remedies, rights, powers
and privileges available at law or in equity, subject to the limitations set
forth in Section 15.1. In the event of a termination of this Agreement under the
provisions of this Article 16, a party not then in material breach of this
Agreement shall stand fully released and discharged of any and all obligations
under this Agreement.

         17. PHYSICIAN EMPLOYMENT AGREEMENT.

         17.1. Physician Employment Agreement. The parties acknowledge that in
accordance with the terms of this Agreement, Physician, as employee, and New
P.C., as employer, have entered into the Physician Employment Agreement and that
Vision 21 is entitled to enforce such Physician Employment Agreement as an
intended third party beneficiary. Physician and Vision 21 acknowledge that
Vision 21 would suffer severe harm in the event of Physician's resignation prior
to the expiration of the five (5) year term of such Physician Employment
Agreement (without first obtaining the written consent of Vision 21) or a breach
or default of Physician's obligations under such Physician Employment Agreement,
and Physician, the Company and Vision 21 agree that Vision 21 shall be entitled
to recover from Physician any and all damages incurred by Vision 21 caused by
such resignation, breach or default. Notwithstanding the foregoing, Vision 21
shall not be entitled to recover its damages caused by such resignation, breach
or default if such resignation, breach or default was caused by: (i) the death
or disability of Physician, (ii) circumstances not caused by an act or omission
of Physician and which circumstances are beyond his control, or (iii) loss of
Physician's license to practice as an ophthalmologist, unless such loss of
license is due to an act or omission of Physician. Notwithstanding the
foregoing, Physician shall have no obligation to pay the damages contemplated in
this Section 17.1 if (a) the Business Management Agreement has been

                                      -59-

<PAGE>   60



terminated pursuant to a material breach by Vision 21, or (b) Physician cures
any such breach or default of the Physician Employment Agreement within a period
of thirty (30) days after notice from Vision 21 of such breach or default.

         17.2. Survival. The parties acknowledge and agree that this Article 17
shall survive the Closing of the transactions contemplated herein.

         18. NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

         18.1. Physician Non-Competition Covenant.

                  a. The Physician recognizes that the covenants of the
Physician contained in this Section 18.1 are an essential part of this Agreement
and that, but for the agreement of the Physician to comply with such covenants,
Vision 21 would not have entered into this Agreement. The Physician acknowledges
and agrees that the Physician's covenant not to compete is necessary to ensure
the continuation of the Management Business (as defined below) and is necessary
to protect the reputation of Vision 21, and that irreparable and irrevocable
harm and damage will be done to Vision 21 if the Physician competes with the
Management Business or Vision 21. The Physician accordingly agrees that for the
periods set forth in the Business Management Agreement, the Physician shall not:

                           i)   directly or indirectly, either as principal,
agent, independent contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's own benefit or
for the benefit of any other person or entity knowingly (A) hire, attempt to
hire, contact or solicit with respect to hiring any employee of Vision 21 (or of
any of its direct or indirect subsidiaries) or (B) induce or otherwise counsel,
advise or encourage any employee of Vision 21 (or of any of its direct or
indirect subsidiaries) to leave the employment of Vision 21;

                           ii)  act or serve, directly or indirectly, as a
principal, agent, independent contractor, consultant, director, officer,
employee, employer or advisor or in any other position or capacity with or for,
or acquire a direct or indirect ownership interest in or otherwise conduct
(whether as stockholder, partner, investor, joint venturer, or as owner of any
other type of interest), any Competing Management Business as such term is
defined herein; provided, however, that this clause (ii) shall not prohibit the
Physician from being the owner of up to 1% of any class of outstanding
securities of any company or entity if such class of securities is publicly
traded; or

                           iii) directly or indirectly, either as principal,
agent, independent, contractor, consultant, director, officer, employee,
employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for the Physician's own benefit or
for the benefit of any other person or entity, call upon or solicit any
customers or clients of the Management Business; provided however, that the
Physician may send out a general notice to the customers or clients of the
Management Business announcing the

                                      -60-

<PAGE>   61



termination of his arrangement with Vision 21 and may advertise in a general
manner without violating this covenant. The parties hereto acknowledge and agree
that for purposes of this Section, patients which have in the past received
medical or optometric care from the Company and/or shall in the future receive
medical or optometric care from the New P.C. are not deemed to be customers or
clients of the Management Business.

                  b. For the purposes of this Section 18.1, the following terms
shall have the meaning set forth below:

                           i) "Management Business" shall mean management and
administration of the non-medical aspects of medical, ophthalmology and
optometry practices.

                           ii) "Competing Management Business" shall mean an
individual, business, corporation, association, firm, undertaking, company,
partnership, joint venture, organization or other entity that either (A)
conducts a business substantially similar to the Management Business within the
State, or (B) provides or sells a service which is the same or substantially
similar to, or otherwise competitive with the services provided by the
Management Business within the State; provided, however, that "Competing
Management Business" shall not include Vision 21, or the Physician's internal
management and administration of the Physician's medical practice or
participation in the management and administration of a physician group in which
the Physician devotes a significant amount of time to the practice of medicine.

                  c. Should any portion of this Section 18.1 be deemed
unenforceable because of the scope, duration or territory encompassed by the
undertakings of the Physician hereunder, and only in such event, then the
Physician and Vision 21 consent and agree to such limitation on scope, duration
or territory as may be finally adjudicated as enforceable by a court of
competent jurisdiction after the exhaustion of all appeals.

                  d. This covenant shall be construed as an agreement ancillary
to the other provisions of this Agreement, and the existence of any claim or
cause of action of the Physician against Vision 21, whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by
Vision 21 of this covenant; provided, however, that the Physician shall not be
bound by this covenant and shall not be obligated to pay the liquidated damages
contemplated in this Section 18.1 if at the time of a breach of this covenant
the Business Management Agreement has already been terminated pursuant to
Section 6.2(a) or 6.2(d) thereof. Without limiting other possible remedies to
Vision 21 for breach of this covenant, the Physician agrees that injunctive or
other equitable relief will be available to enforce the covenants of this
provision, such relief to be without the necessity of posting a bond, cash or
otherwise. The Physician and Vision 21 further expressly acknowledge that the
damages that would result from a violation of this non-competition covenant
would be impossible to predict with any degree of certainty, and agree that
liquidated damages in the amount of the aggregate consideration received by the
Physician pursuant to this Agreement is reasonable in light of the severe harm
to the Management Business and Vision 21 which would result in the event that a
violation of this non-competition covenant were to occur. For purposes of
calculation of the

                                      -61-

<PAGE>   62



liquidated damages contemplated in this Section and for purposes of calculation
of the liquidated damages contemplated in the Business Management Agreement and
the Physician Employment Agreement between the Physician and New P.C., the
aggregate consideration received by Physician pursuant to this Agreement shall
be in those amounts and in such form as set forth in Schedule 18.1. If the
Physician violates this non-competition covenant, Vision 21 shall, in addition
to all other rights and remedies available at law or equity, be entitled to (a)
cancel the number of shares of Common Stock held by the Physician or, with
respect to shares of Common Stock entitled to be received by the Physician,
terminate its obligation to deliver such number of shares of Common Stock valued
as set forth in Section 6.6(a) of the Business Management Agreement, and (b)
repayment by Physician to Vision 21 of any and all sums received in connection
with any shares of Vision 21 Common Stock sold by Physician; but in no event
shall Vision 21 be entitled to offset amounts in excess of the liquidated
damages sum pursuant to this Section 18.1. The Physician agrees to deliver to
Vision 21 the certificates representing any such shares canceled by Vision 21.
Payment and satisfaction by Physician shall be made within sixty (60) days of
notification to Physician by Vision 21 that Physician has violated this
non-competition covenant.

                  e. Notwithstanding anything contained herein, this Section
18.1 shall not be construed to (i) limit the freedom of any patient of the
Physician to choose the facility or physician from whom such patient shall
receive health-care services or (ii) limit or interfere with the Physician's
ability to exercise his professional medical judgment in treating his patients
or his ability to provide medical services to his patients.

         18.2. Physician Confidentiality Covenant. From the date hereof, the
Physician shall not, directly or indirectly, use for any purpose, other than in
connection with the performance of the Physician's duties under the Physician
Employment Agreement with New P.C., or disclose to any third party, any
information of Vision 21 or the Company, as appropriate (whether written or
oral), including any business management or economic studies, patient lists,
proprietary forms, proprietary business or management methods, marketing data,
fee schedules, or trade secrets of Vision 21 or of the Company, as applicable,
and including the terms and provisions of this Agreement and any transaction or
document executed by the parties pursuant to this Agreement. Notwithstanding the
foregoing, the Physician may disclose information that the Physician can
establish (a) is or becomes generally available to and known by the public or
medical community (other than as a result of an unpermitted disclosure directly
or indirectly by the Physician or his Affiliates, advisors, or representatives);
(b) is or becomes available to the Physician on a nonconfidential basis from a
source other than Vision 21, the Company or their respective Affiliates,
advisors or representatives, provided that such source is not and was not bound
by a confidentiality agreement with or other obligation of secrecy to Vision 21,
the Company or their respective Affiliates, advisors or representatives of which
the Physician has knowledge; or (c) has already been or is hereafter
independently acquired or developed by the Physician without violating any
confidentiality agreement with or other obligation of secrecy to Vision 21, the
Company or their respective Affiliates, advisors or representatives. Without
limiting the other possible remedies to Vision 21 for the breach of this
covenant, the Physician agrees that injunctive or other equitable relief shall
be available to enforce this covenant, such

                                      -62-

<PAGE>   63



relief to be without the necessity of posting a bond, cash or otherwise. The
Physician further agrees that if any restriction contained in this Section 18.2
is held by any court to be unenforceable or unreasonable, a lesser restriction
shall be enforced in its place and the remaining restrictions contained herein
shall be enforced independently of each other.

         18.3. Survival. The parties acknowledge and agree that this Article 19
shall survive the Closing of the transactions contemplated herein.

         19. DISPUTES.

         19.1. Mediation and Arbitration. Any dispute, controversy or claim
(excluding claims arising out of an alleged breach of Article 18 of this
Agreement) arising out of this Agreement, or the breach thereof, that cannot be
settled through negotiation shall be settled (a) first, by the parties trying in
good faith to settle the dispute by mediation under the Commercial Mediation
Rules of the AAA (such mediation session to be held in Tampa, Florida, if the
amount in dispute is equal to or in excess of $200,000 or if the dispute is
solely of a non-monetary nature, and in Tucson, Arizona if the amount in dispute
is lower than $200,000, and in either case to commence within 15 days of the
appointment of the mediator by the AAA), and (b) if the controversy, claim or
dispute cannot be settled by mediation, then by arbitration administered by the
AAA under its Commercial Arbitration Rules (such arbitration to be held in
Tampa, Florida, if the amount in dispute is equal to or in excess of $200,000 or
if the dispute is solely of a non-monetary nature, and in Tucson, Arizona if the

by the AAA), and judgment on the award rendered by the arbitrator may be entered
in any court having jurisdiction thereof.

Schedules hereto and thereto, constitutes the entire agreement between the

subsidiary. In the event of such assignment, Vision 21 shall remain liable
hereunder.

         20.10. Attorneys' Fees. Except as otherwise specifically provided
herein, if any action or proceeding is brought by any party with respect to this

WEDNESDAY, SEPTEMBER 17, 8:14 AM EDT
COMPANY PRESS RELEASE

Vision Twenty-One, Inc. Completes Three Acquisitions;
Expands Local Area Delivery Systems

         LARGO, Fla., Sept. 17/PRNewswire/ -- Vision Twenty-One, Inc.
(NASDAQ:EYES), an eye care practice management company, today announced the
acquisition of the operating assets of Florida Eye Center, Managed Health
Services (MHS) and Retina Associates, Southwest, P.C.  These acquisitions are
consistent with the Company's strategy to develop Local Area Delivery Systems
(LADS).

         The transactions have closed in escrow pending finalization of certain
closing items and are accretive to Vision Twenty-One Inc.'s earnings on a pro
forma basis.  Aggregate consideration for these acquisitions was approximately
$8.6 million, consisting of cash in the amount of $3.6 million and 490,000
shares of Vision Twenty-One, Inc. common stock.  The consideration is subject
to certain adjustments.

         Vision Twenty-One, Inc. will manage the centers pursuant to its
40-year Management Agreement.  Florida Eye Center, located in Tampa, Florida,
is a five-ophthalmologist multi-specialty practice with two locations and an
optical dispensary.  Retina Associates, Southwest is a three-physician premier
sub-specialty retina practice.  Retina has two offices located in Tucson,
Arizona.  These practices had combined clinic revenues of $6.9 million for the
year ended December 31, 1996.  On a pro forma basis, these transactions would
have added $4.4 million in practice management fee revenue.

         Vision Twenty-One, Inc. also acquired Managed Health Services (MHS), a
managed-care company.  MHS is located in Tampa, Florida, and consists of 28
contract providers (26 M.D.'s and 2 O.D.'s), with existing contracts covering
over 83,000 capitated ophthalmology lives in Florida.  The revenues from MHS
were $1.8 million for the year ended December 31, 1996.

         Additionally, Vision Twenty-One, Inc. opened two optometry clinics
located inside retail centers in Louisiana in September 1997.

         Theodore N. Gillette, Chairman, President and Chief Executive Officer
of Vision Twenty-One, Inc. stated: "These acquisitions continue Vision
Twenty-One's strategy of developing our Local Area Delivery Systems.  Through
the integration process, eye care patients will receive comprehensive quality
eye care through cost-efficient services in strategic geographic networks."

<PAGE>   2

         Vision Twenty-One, Inc. successfully completed its Initial Public
Offering of 2,100,000 shares of common stock at $10.00 per share on August 18,
1997.  The Company's common stock, traded on NASDAQ, closed at the end of the
day September 16, 1997, at $14.00 per share.

         Vision Twenty-One, Inc. provides a wide range of management and
administrative services to its LADS, which are integrated networks of
optometrists, ophthalmologists, ASCs and retail optical centers.  LADS are
designed to offer the full continuum of eye care services in local markets
served by the Company.  Vision Twenty-One, Inc. currently provides its services
to 11 LADS located in six states through which 660 Affiliated Providers deliver
eye care services.

         Statements contained in this press release that are not based on
historical fact, including statements of revenues and future expansion of
Vision Twenty-One, Inc. are forward-looking statements.  These forward-looking
statements contain statements regarding expected future profitability to the
Company resulting from the acquisitions, the quality of eye care by managed
providers affiliated with the Company, the integration of the Company's Local
Area Delivery System, and the cost efficiency of service delivered by these
managed providers.  Actual results may differ materially from the statements
made as a result of various factors including, but not limited to, the risks
associated with the Company's ability to finance future growth; the loss of
significant management contract(s); profitability at sites managed by Vision
Twenty-One, Inc.; the ability of the Company to successfully integrate the
acquisitions, the ability of the Company to effectively manage the cost of the
acquisitions; any material impact on future revenues of the acquired
businesses; changes in insurance coverage, government laws and regulations
regarding health care or managed care contracting; the ability of the Company
to retain managed care contracts with acceptable terms; and other risks,
including those identified in the Company's most recent S-1 registration
statement and in other documents filed by the Company with the U.S. Securities
and Exchange Commission (SEC).
